ThesisItem Open Access PHYSIOLOGICAL AND BIOCHEMICAL INVESTIGATION ON LEAF REDDENING IN Bt AND NON Bt COTTON (Gossypium spp.).(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2017-09-16) RAUT, SUMIT MURLIDHAR.; DURGE, Dr. D. V.Cotton is an important commercial fibre crop of global significance which plays a dominant role in world agriculture and industrial economy. India is important grower of cotton on a global scale. Among the production constraints leaf reddening is the predominant problem of Bt cotton growers which became issue of debet for ascertaining the causes and remedies for leaf reddening. To ascertain the role of nutrients in leaf reddening, the present field experiment entitled, “Physiological and biochemical investigation on leaf reddening in Bt and non Bt Cotton (Gossypium spp.)" was carried out at AICCP, experimental field of Cotton Research Unit, Dr. PDKV Akola, (M.S.) during Kharif season of 2013-14 and 2014-15 in split plot design replicated thrice. Main plot treatments consisted of three hybrids [viz., Mallika (Bt), RCH 2 (Bt) and PKV Hybrid 2 (non Bt)], sub plot treatments were two fertilizer doses [viz., 100% RDF and 125% RDF]. Sub-sub plot treatments consisted of seven different chemical sprays [viz., 2% Urea, 2% DAP, 2% KNO3, 1% MgSO4, 500 ppm Cycocel, irrigation and control]. Thus, 42 treatment combinations were formed. The fertilizer dose for Bt (120:60:60 NPK kg/ha) and non Bt cotton (60:30:30 NPK kg/ha) was applied in two split doses. At the time of sowing 50% N and full dose of P and K was applied and remaining N was applied after 30 DAS. The two foliar sprays were given at 60 and 80 DAS. The recommended package of practices was followed during course of investigation. Besides the yield data, periodical observations on morphological (plant height, leaf area plant-1, dry matter plant-1 and red leaf incidence), physiological (photosynthetic efficiency and relative water content) and biochemical (cell sap pH, total chlorophyll, N, Mg, anthocyanin, proline and carbohydrate content of leaf) parameters were recorded at 60, 80, 100 and 120 DAS. The Phenological observations were also recorded. Soil fertility status (available N, P and K) were recorded before sowing and after harvesting in both the years. The observations on sucking pest (number of leafhopper, aphids, thrips and whitefly leaf-1) were also recorded. The experimental evidences pointed out that the incidence of leaf reddening was more in Bt cotton than non Bt cotton. The minimum intensity of reddening in Bt and non Bt cotton was observed in the treatment combination of 125 % RDF + foliar sprays with KNO3 and MgSO4. Among the foliar sprays 2% KNO3 (60 and 80 DAS) had shown minimum leaf reddening, However, the treatment combination (125 % RDF + 1 % MgSO4) was found to be the best for highest total chlorophyll content. The study also revealed that the mineral nutrients, which were mostly responsible for reddening viz., nitrogen and magnesium content in leaves, were decreased as the crop growth stage advanced. The PKV Hybrid 2 recorded maximum cell sap pH, total chlorophyll, leaf nitrogen and magnesium content than the Bt cotton hybrids. In case of fertilizer dose, 125% RDF and foliar sprays of 2% KNO3 and 1% MgSO4 maintained higher cell sap pH, total chlorophyll, nitrogen, and magnesium content of leaves in non Bt cotton than Bt cotton. Accumulation of highest proline, anthocyanin and carbohydrate were found in reddening affected leaves. It was evident that, the application of 125% RDF showed 9.21 % reduction in leaf reddening incidence. Similarly 16.14% increased seed cotton yield per plant with application of 125% RDF over 100% RDF. Per cent reduction of red leaf incidence was recorded 18.33% in 2% KNO3 treated plot followed by 1% MgSO4 i.e. 14.76% over control. Seed cotton yield per plant was increased by 39.33% in 2% KNO3 treated plot followed by 1% MgSO4 sprayed plot i.e. 31.88% over the control (untreated plots). Application of 125% RDF and the two foliar sprays of 2% KNO3 and 1% MgSO4 at 60 and 80 DAS had reduced the risk of leaf reddening as well as helped in increasing seed cotton yield in Bt and non Bt cotton hybrids at Akola conditions. It is concluded from the present study that the reduction in chlorophyll, nitrogen and magnesium content in plant at boll development stage was the cause of reddening in Bt and non Bt cotton. This study also suggested that, the nutrients were one of the causes for leaf reddening. Bt cotton had more nutrients requirement especially at boll development stage, which was fulfilled by the foliar sprays. Hence, present study also provides future guide line of research for various combinations of nutrients for foliar sprays for Bt cotton hybrids at different development stages, which can reduce leaf reddening and there by yield sustainability can be achieved.ThesisItem Open Access EVALUATION OF AMERICAN COTTON GENOTYPES FOR SUCKING PESTS TOLERANCE.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2017-09-14) WAKODE, YOGESH SHAMRAO; Deshmukh, Dr. S. B.An experiment on “Evaluation of American Cotton Genotypes for Sucking Pests Tolerance” was conducted at Cotton Research Unit, Dr. Panjabrao Deshmukh Krishi Vidypeeth, Akola during Kharif, 2016-17. Twenty one cotton genotypes were replicated thrice under Randomized Block Design and evaluated for tolerance against sucking pests. The data were recorded on population of sucking pests/leaves at 45 and 60 DAS. Similarly, the data were also collected on physico-morphic traits like hair density (trichome) and number of gossypol glands/cm2to determine tolerance /susceptibility of cotton genotypes against sucking pest. Besides this biochemical parameters like reducing sugar, nitrogen and protein content in leaves were estimated by standard procedure at 45 and 60 DAS. The observations were recorded on yield and yield contributing characters viz., days to 50 per cent flowering, day to 50 per cent boll bursting, plant height (cm), number of monopodia per plant, number of sympodia per plant, number of bolls per plant, seed cotton yield per plant (g). The detailed findings of the study is presented below It was observed from present study that those genotypes having more trichome density and gossypol glands/cm2 recorded lower population of aphids, leafhoppers and thrips but population of whiteflies on these genotypes was more indicating role of trichome density and gossypol gland in sucking pest resistance. Highest number of hair density (trichomes/cm2) was noted in AKH-2013-3 followed by DHY-286, AKH-1523 and AKH-1524. Highest number of gossypol glands/cm2 was noted in genotype DHY-286 followed by AKH-1301 and AKH-2013-3. The results indicating that genotypes with higher contents of reducing sugar, nitrogen and protein suffer from the attack of aphids, leafhoppers and thrips. Reducing sugar content was minimum in genotype DHY-286 followed by AKH-2013-3, AKH-1523 and AKH-1524. The minimum nitrogen content was in DHY-286 followed by AKH-2013-3 and AKH-1524. Least protein content was noted in DHY-286 followed by AKH-2013-3, AKH-10-3 and AKH-1524. The hair density (trichomes/ cm2) at 45 and 60 DAS on leaf of cotton had negative and significant correlation with number of aphids, leafhoppers, and thrips at 45 and 60 DAS. The reducing sugar, nitrogen content and protein content at 45 and 60 DAS had positive significant correlation with number of aphids, leafhopper and thrips at 45 and 60 DAS. Seed cotton yield had positive and significant correlation with number of bolls and number of sympodia per plant. Finally it is concluded that cotton genotypes viz., AKH-2013-3, DHY-286, AKH-1524, AKH-1523, AKH-1522, AKH-2013-4, AKH-10-2, AKH-10-3, AKH-1302 proved effective to combat the menace of sucking pests as these genotypes are having more trichome density and gossypol glands and these genotypes posses less reducing sugar, nitrogen content and protein content. Moreover, these genotypes also showed the association of the various physicomorphic traits (viz., trichome density and number gossypol glands) and biochemical (reducing sugar, nitrogen and protein content) traits regulating the tolerance in cotton against sucking pests. The correlation studies revealed that the hair density (trichomes) on leaf of cotton had negative and significant correlation with population of aphids, leafhoppers, and thrips. The hair density (trichomes) on leaf of cotton had positive and significant correlation with population of whiteflies. The reducing sugar, nitrogen content and protein content had positive significant correlation with population of aphids, leafhopper and thrips. The reducing sugar, nitrogen content and protein content had negative significant correlation with population of whiteflies.ThesisItem Open Access Evaluation for heterosis and combining ability in okra (Abelmoschus esculentus (L) Moench)(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, 2017-06-21) Nama, Nirmala Devi; Kayande, Dr. N.V.The present study entitled “Evaluation for heterosis and combining ability in okra” was carried out with objectives to study the heterosis and combining ability effects in different genotypes of okra using Line X Tester analysis (Kempthorne, 1957). The crosses were affected using four lines (females) viz., MTPH, 11-1, NO-3 and 38HU and seven testers (males) viz., 14-11-5, 11-14, PF, 11-6, BH-55, 93M and AKOV-107. Eleven parents and their crosses along with the standard check Exp Hy-1 (Mahyco) have been evaluated in randomized block design with two replications at the experimental farm of Chilli and Vegetable research unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra during kharif, 2016. The data was recorded on fourteen characters viz., days to initiation of flowering, days required for 50 percent flowering, days required to first harvesting, plant height, Internode length, number of branches per plant, number of internodes per plant, fruit length, breadth of the fruit, fruit weight, number of fruits per plant, green fruit yield per plant, green fruit yield per plot, green fruit yield per hectare. The highest mean performance was recorded in 38HU X 11-14(268.45%) followed by 38HU X 11-6 (266.15%) and 38HU x 14-11-5 (259.4%) for yield per plant. The highest and significant average heterosis for yield per plant was recorded by cross combination 38HU X 11-6 (44.98%) followed by 38HU X 11-14 (55.07%). The maximum significant heterobeltiosis for yield per plant was recorded by the cross 38HU X 11-6 (36.65%) followed by 38HU X 11-14 (53.07%). The highest standard heterosis over check Exp Hy-1 for yield per plant was recorded by 38HU X 11-14 (37.60%) followed by 38HU X 11-6 (36.42%) and 38HU X 14-11-5 (32.97%). Among the parents two lines (38HU and MTPH) and four testers (14-11-5, 11-14, PF and 11-6) were found to be good general combiners for yield per plant along with the most of the yield contributing traits. Thus these parents should be included in further hybridization programme. High sca effects for yield per plant were recorded by 11-1 x 14-11-5 (41.58) followed by 38HU X 11-14 (40.47) and MPTH X AKOV-107 (36.45). These crosses also recorded the sca effects for most of the yield contributing traits. On the basis of mean performance, heterosis and sca effects of crosses, twelve crosses viz., 11-1 x 14-11-5, 38HU X 11-14, MPTH X AKOV-107, MPTH X 93M, NO-3 X 11-6, NO-3 X AKOV-107, NO-3 X BH-55, 11-1 X PF, 38HU X PF, 11-1 X BH-55, 38HU X 11-6 and 38HU X 14-11-5 were identified as promising crosses for fruit yield per plant. Hence these crosses should be tested in preliminary or multilocation trails for further commercial exploitation.ThesisItem Open Access “STABILITY ANALYSIS FOR GRAIN YIELD AND IT’S COMPONENTS OF ADVANCED BREEDING LINES IN MUNGBEAN (Vigna radiata (L.) Wilczek) ”(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola., 2017-08-19) BORUDE, GOVARDHAN RAMKISANRAO.; PATIL, DR. A.N.The present investigation in mungbean was undertaken with a view to detect genotype x environment (G x E) interaction for grain yield and its components of advanced breeding lines in mungbean and to identify genotypes suitable for different predictable environments. Sixteen genotypes were sown on three different sowing dates in Randomised Block Design, with three replications for measuring the stability of genotypes for different characters. The data was subjected to statistical analysis by following the approach given by Eberhart and Russell (1966). In general, genotypic differences were found significant for fourteen characters indicating the presence of genetic diversity in the genotypes and the character plant height at maturity. Linear component of G x E interaction was significant for the characters days to maturity, plant height at maturity, number of cluster per plant, number of pods per plant, seed yield per plant and harvest index. Whereas pooled deviation were found significant for characters viz., days to 50% flowering, number of primary branches per plant, number of pod per cluster, number of seeds per pod, seed yield per plot and seed yield per hectare. Estimates of environmental indicate (lj) suggested that E1 environment i.e. sowing on 7th June was found to be most favorable for the seed yield and important yield contributing characters. None of the genotype was found stable for all characters under study. The genotype viz., AKM-10-21 showed average stability for earliness in flowering. Genotypes AKM-10-5, AKM-10-21, AKM-12-04, AKM-12-06, AKM-12-15 and AKM-12-22 exhibited average stability for earliness in maturity, whereas, AKM-12-28 showed above average stability. AKM-10-5, AKM-10-11, AKM-12-12, AKM-12-22 and AKM-12-24 showed average stable performance for plant height at maturity (cm). For primary branches per plant among all the genotypes, AKM-12-06 and PKV AKM-4 (ch) showed wider adaptability. Genotype AKM-12-06, showed the wider adaptability for number of clusters per plant. Genotype AKM-12-14, AKM-12-22, AKM-12-28 and PKV AKM-4 (ch), showed the wider adaptability for number of pods per cluster. The genotype AKM-12-24 was showed average stability over all types of environments for number of pods per plant whereas AKM-12-06, AKM-12-22, AKM-12-23 and PKV AKM-4 (ch) recorded below average stability. For pod length, among all the genotypes, AKM-10-11 and AKM-10-21 showed wider adaptability. Genotypes AKM-10-5 and BM 2003-2 (ch) showed wider adaptability for 100 seed weight (g), suggesting their stability for all types of environments. Genotype AKM-10-11, AKM-12-12, AKM-12-22 and AKM-12-24 recorded average stability for seed yield per plant (g) and found suitable for all type of environment. Genotypes AKM-10-11, AKM-12-14, AKM-12-22, AKM-12-23, PKV AKM-4 (ch) and BM 2003-2 (ch) showed below average stability for harvest index whereas AKM- 10-5 showed above average stability. Genotypes AKM-12-23,AKM-12-24, AKM-12-28 and BM 2003-2 (ch) recorded average stability for seed yield per plot (g) and found suitable for all type of environment, while AKM-12-12 showed above average stability and PKV AKM-4 (ch) recorded below average stability. Above average stability was exhibited by very few genotypes. Most of the genotypes showed below average stability for most of the characters under study because of wide range of environments and unfavorable climatic conditions during the period of investigations.ThesisItem Open Access Evaluation and molecular characterization of vegetable type pigeonpea [Cajanus cajan (L)] genotype for nutritional quality and yield attributing traits.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, 2017-06-30) SINGH, SANDEEP KUMAR; Nandanwar, Dr. R.S.The present investigation entitled “Evaluation and molecular characterization of vegetable type pigeonpea [Cajanus cajan (L)] genotype for nutritional quality and yield attributing traits” was conducted in the experimental field of Department of Agricultural Botany, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra state during Kharif of 2016-2017 to elucidate the information about evaluation and identification of desirable vegetable type pigeon pea [Cajanus cajan (L.)] genotype for nutritional quality and yield attributing traits as well as to assessing genetic analysis for morpho-physiological, nutritional quality and yield attributing traits. The study also depicted the information about molecular characterization of promising vegetable type pigeon pea genotypes. Six nutritional traits viz. carbohydrate, protein, calcium, iron, manganese, and zinc revealed that the green stage legumes had higher amounts of minerals viz., iron and zinc. However the grain stage legumes had higher amount of protein, starch manganese and calcium. The Principal component analysis (PCA) revealed that 71.50% of the total diversity was explained on the basis of the first four principal components. The first principal component (PC1) had the highest Eigen value of 3.649 and explained 26.064% of total variation. Whereas, the fourth principal component (PC4) accounted for only 9.827% of the variation with an Eigen value of 1.376, which is the lowest value among the four principal components. The cluster diagram which was done to evaluate the sixteen genotypes based on nutritional data, yield attributing characters and morrpho-physiological traits respectively revealed that overall four clusters were formed in cluster diagram based on nutritional data; five clusters were generated for yield attributing characters whereas only three clusters were generated for morpho-physiological traits, which showed a wide range of variability between the genotypes under study. The second objective of the study was genetic analysis for morpho-physiological, nutritional quality and yield attributing traits. The field component of the experiment included sixteen genotypes of pigeonpea that spread over season, Kharif,2016-17. The crop was grown in three replications using two lines for each of the genotype. The observations recorded were days to 50 % flowering, fresh pod colour, flower petal colour, plant height, leaf area index both (R6 and R8), chlorophyll content index both (R6 and R8), Days to harvest at first flush for vegetable purpose (R6), number of primary branches per plant, 100 fresh pod weight, 100 fresh seed weight, pod length, pod width and green pod yield per plant. A wide range of variability was observed for all the characters. The estimates of phenotypic coefficients of variation were higher than that of genotypic coefficients of variation for all characters under study. The estimates of genotypic correlation coefficient were higher than phenotypic correlation coefficient, indicating little masking effect environment on the expression of the characters. The best genotype for green pod yield was found BDN-716. High heritability accompanied with high genetic advance was observed for the trait 100 fresh pod weights. This trait can be used for selection in the further breeding programmes. Molecular characterization of promising vegetable type pigeon pea genotypes showed highest similarity (0.762) between AMAR and AKTM-11-06, whereas the lowest similarity coefficient was observed between SKN-0632 and AKTM-11-06 with a similarity coefficient value of (0.056). UPGMA dendrogram constructed using Jaccard’s similarity coefficient gave the clustering of pigeonpea genotypes. The genotypes were clustered into two super clusters viz. super cluster-I and super cluster-II. The cluster analysis revealed that high diversity was observed in PKV-TARA and AKTM-1644. These diverse genotypes may be used as valuable sources for breeding programmes.ThesisItem Open Access EVALUATION OF NEW RESTORER LINES FOR HETEROTIC RESPONSE AND COMBINING ABILITY IN SUNFLOWER (HELIANTHUS ANNUUS L.)(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, 2017-06-29) SAHANE, GAJANAN SANDU.; Nichal, Dr. S.S.The present study entitled “Evaluation of new restorer lines for heterotic response and combining ability in sunflower (Helianthus annuus L.)” was under taken to estimate the extent of heterosis and combining ability effects in sunflower genotypes using Line X Tester analysis (Kempthorne, 1957). The experimental material consist of 14 parents (five CMS lines and nine testers) and their 45 F1’s (crosses) along with standard check DRSH-1 were evaluated in RBD with three replications at the field of Oilseed Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif 2016. The data was recorded on ten characters viz., days to 50% flowering, days to maturity, plant height, head diameter, 100 seed weight, volume weight, seed filling percentage, hull content, oil content and seed yield per plant. The highest and significant average heterosis and heterobeltiosis for seed yield per plant was recorded by cross combination AKSF-14-1A x P-146R (338.84% & 315.48%) followed AKSF-14-2A x IR-1-1R (291.24% & 254.94%). The highest standard heterosis over best check i.e. DRSH-1 for seed yield per plant was recorded by AKSF-14-1A x EC-601951R (47.21%), followed by cross AKSF-14-2A X IR-1-1R (41.91%) and AKSF-14-2A x AKSF-14R (40.66%). The cross, MS-400A X EC-601951R recorded significant positive standard heterosis over check for seed yield (29.38%) and oil content (4.07%). Among the parents AKSF-14-2A, EC-601951R and IR-1-1R were found to be best general combiners for most of the yield contributing traits, seed yield and also for oil content, thus these parents should be included in future hybridization programme for improvement in seed yield as well as oil content in sunflower. The highest significant sca effect for seed yield was recorded by the cross AKSF-14-1A X P-146R (11.03) followed by CMS-2A X R-16 (10.84), AKSF-14-2A X AKSF-14R (10.59) and AKSF-10-1-1A X P-146R (10.45). Three combinations viz., CMS-2A X R-16, AKSF-14-1A X IR-1-1R and MS-400A X EC-601951R recorded highly significant sca effects for oil content as well as for seed yield. On the basis of mean performance, heterosis and sca effects of crosses, three crosses viz., AKSF-14-1A X EC-601951R, AKSF-14-2A X IR-1-1R and AKSF-14-2A X AKSF-14R are identified as promising crosses for seed yield and the cross MS-400A X EC-601951R is identified as promising cross for seed as well as oil content thus, these crosses needs further evalution in preliminary or multilocation hybrid trials for further commercial exploitation.ThesisItem Open Access EFFECT OF SEED STORAGE TECHNIQUES ON SEED QUALITY AND FIELD PERFORMANCE OF SOYBEAN (Glycine max (L.) merril)”(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola., 2017-07-27) WAKODE, SNEHAL KESHAORAO.; NANDANWAR, DR. R.S.Soybean is an important crop in India but the lack of availability of quality seed at proper time is one of the important reasons for low productivity in soybean. Seed can store satisfactorily under control condition with low temperature and low moisture .Therefore, rapid loss of seed viability and vigour takes place during storage at ambient temperature. Among the several factors affecting seed storability, seed moisture is also responsible for reduction of germination and vigour. The efforts were made to identify the proper seed storage technique with safe seed storage moisture at Seed Technology Research Unit, Dr.PDKV, Akola (MS).A present study on entitled “Effect of Seed Storage Techniques on Seed Quality and Field Performance of Soybean (Glycine Max (L.) Merrill)”was conducted during 2014-2015 at laboratory and kharif season of 2015-2016 at experimental field. The freshly harvested seed of soybean var. JS-335 were stored in different storage container like polythene bag, cloth bag and airtight container along with silica gel and desiccant beads under ambient condition up to next sowing season. The bimonthly observations were recorded on seed quality parameters in laboratory during storage. The same seed sample was used for sowing in field to assess the field performance. The experimental results exhibited that seed quality parameters differed significantly due to different packing material during storage. Among the treatments the seed stored in airtight container along with silica gel showed significant i.e.heigher seed germination and vigour index during storage. The same treatment performed better in field also significantly maximum plant stand, number pods per plant and height seed yield was recorded in this treatment. However the effect of different storage technique on 100 seed weight was found to be non-significant. Hence the seeds stored in airtight container along with silica gel showed significant result in maintaining seed quality during storage and enhanced the seed yield of soybean.ThesisItem Unknown ASSESSMENT OF SEED VIGOUR TRAITS IN ARBOREUM COTTON.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2017-08-18) UKEY, BHARAT NAMDEO.; Ujjainkar, DR.V. V.An experiment was conducted entitled “Assessment of seed vigour traits in arboreum cotton”. Which was conducted at Seed Technology Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth Akola, during the Kharif season of 2015 - 2016. Five genotypes of arboreum cotton including three varieties viz., AKA-7, AKA-8, and AKA-2005-3 along with two GMS based hybrids viz., PKVSuvarna and PKVDH-1 for this study. The evaluation of six vigour traits was done in Completely Randomize Block Design, whereas sixteen yield and yield contributing traits were analysed from field experiments laid down in Randomized Block Design with five treatments and four replication. The objectives of the present study were to estimate the mean performance of seed vigour traits in arboreum cotton and to assess the correlation between seed vigour traits and yield contributing characters in arboreum cotton. The observation were recorded on six seed vigour traits including germination per cent, root length, shoot length, seedling dry weight, seed vigour index-I and seed vigour index-II in laboratory. Whereas sixteen yield contributing characters viz., field emergence per cent, days to first flowering, days to 50% flowering, days to 50% boll bursting, plant height, number of monopodia per plant, number of sympodia per plant, number of boll per plant, number of seed per boll, boll weight, seed index, lint index, ginning per cent, oil per cent, seed cotton yield per plant and lint yield per plant were recorded. The analysis of variance revealed the substantial variability in experimental material except that of ginning per cent. Both the hybrids viz., PKVSuvarna and PKVDH-1 exhibited superiority for all six vigour traits in comparison to three varieties. Among the varieties AKA-2005-3 performed better for vigour traits over AKA-7 and AKA-8. The difference among the treatments were statistically significant for all vigour traits. The data were subjected to simple correlation (r) to determine relationship of each vigour trait with yield and its contributing characters, except that of ginning per cen. Almost all yields and its contributing traits exhibited significant positive correlation except that of lint index. For all traits and number of monopodia for germination per cent, root length, seedling dry weight and seed vigour index-II and field emergence per cent found significantly correlated with all seed vigour traits. The positive and highly significant correlation were recorded in between seed cotton yield per plant and all six vigour traits viz., germination per cent (r=0.956*), root length (r=0.957*), shoot length (r=0.957*), seedling dry weight (r=0.983**), seed vigour index-I (r=0.967*) and seed vigour index-II (r=0.942*). Hence, prediction of seed vigour traits in the laboratory is possible and was effective for the determination of yield potential in arboreum cotton.ThesisItem Open Access ASSESSMENT OF SEED QUALITY, GROWTH PARAMETERS AND YIELD IN KHARIF SORGHUM (Sorghum bicolor (L.) Moench)(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola., 2017-11-30) KATHALKAR, PRAJWAL BALKRUSHNA.; Kalpande, Dr. V. V.A present investigation entitled “Assessment of seed quality, growth parameters and yield in kharif sorghum (Sorghum bicolor (L.) Moench)” was conducted to estimate the genetic variability, heritability, genetic advance and correlation between seed quality, growth parameters and yield. The experiment was conducted during kharif season of 2016 using Randomized Block Design with three replications. Observations were recorded for each genotype on seventeen different characters namely days to 50% flowering, plant height (cm), number of leaves, panicle length (cm), seed hardness (kg/cm2), threshed grain mold rating (%), specific gravity of seed (g/ml), germination percentage of seed, electrical conductivity (dsm-1), 1000 seed weight (g), shoot length (cm), root length (cm), root shoot ratio, vigour index length, vigour index mass, fodder yield per plant (g) and grain yield per plant (g). The ANOVA revealed highly significant difference among the all genotypes for all the characters studied indicating the presence of substantial amount of genetic variability. The GCV, PCV, heritability and EGA were estimated for all the characters. The characters threshed grain mold rating and electrical conductivity showed high GCV and PCV values. Highest heritability estimate in broad sense was observed for the character fodder yield per plant. The highest value of expected genetic advance over mean was recorded for the character threshed grain mold rating. For the development of high yielding hybrids in sorghum, panicle length should be considered during selection. Due weitage should be given to plant height and number of leaves in developing high fodder yielding hybrids in sorghum. Similarly seed hardness should be taken in to consideration for improvement in the germination percentage of seed. For grain yield per plant, the ten hybrids viz., AKMS 90 A x AKR 544, ICS 279 A x AKR 544, ICS 279 A x AKR 536, AKMS 90 A x AKR 325-1, AKMS 90 A x AKR 535, AKMS 30 A x AKR 492-1, ICS 89022 A x AKR 547, AKMS 30 A x AKR 527, AKMS 90 A x AKR 337 and AKMS 30 A x AKR 520 were significantly superior over the national check hybrid CSH-35 along with substantial percentage increase over the check. These ten hybrids hold promise in developing high grain yielding hybrids. For development of dual purpose hybrids, two hybrids i.e. AKMS 90 A x AKR 544 and AKMS 30 A x AKR 492-1 appeared best because of their good grain yield along with good fodder yield as compared to the national check hybrid CSH-35. To develop single cut fodder hybrid, the cross ICS 89022 A x AKR 325-1 with highest fodder yield per plant of 199.93 g need to be exploited.
