ThesisItem Open Access Title: EVALUATION OF ORGANICALLY GROWN COTTON GENOTYPES FOR INSECT PESTS TOLERANCE.(Dr.Panjabrao Deashmukh,Krishi Vidyapeet,Akola, 2021-08-13) Authors: AHERKAR, SHRADHA SHRIKANT.; Advisor: Deshmukh, Dr. S. B.Abstract: The research work entitled, “Evaluation of organically grown cotton genotypes for insect pest tolerance” conducted at Centre of Organic Agriculture Research and Training (COART), Department of Agronomy, Dr. PDKV, Akola during the kharif season 2020-21; was undertaken to study the reaction of cotton genotypes against insect-pest under organic condition as well as to study the correlation between the insect-pest with its associated characters and seed cotton yield. The experiment comprised of 22 cotton genotypes (20 SGF cotton genotypes and one resistant check DHY-286 and one susceptible check DCH-32) which were replicated thrice under Randomized Block Design. The data regarding sucking pest was recorded at 45, 60, 90 and 120 DAS, whereas, per cent bollworm infestation was recorded at 60, 90 and 120 DAS. In the similar way, data of morpho-physiological characters i.e. number of gossypol glands per cm2, hair (trichomes) density per cm2 and chlorophyll content index; data of biochemical characters i.e. total soluble sugar, total nitrogen and crude protein was recorded at 45, 60, 90 and 120 DAS. The observations on yield and yield contributing characters i.e. days to 50 per cent flowering, days to 50 per cent boll bursting, plant height, number of bolls per plant, boll weight, number of sympodia per plant, number of monopodia per plant and seed cotton yield were recorded at maturity stage of the cotton crop. From the present study, it was concluded that, genotypes AKH-9916, AV-C14, DHY-286, AKH 09-5, Nirmal 996 and GA-8004 recorded maximum trichome density per cm2 as well as maximum gossypol glands per cm2, however, on the other hand, less amount of chlorophyll content, total soluble sugar, total nitrogen and crude protein was recorded in these genotypes. These genotypes also recorded least population of aphids, leafhoppers, thrips and less per cent bollworm infestation. Whereas, genotypes GH-8032, DCH-32, Chetna-S1, Raja-954 and Bhakti-245 had tolerant reaction towards whitefly and showed less trichome density per cm2 and less gossypol glands per cm2 but these genotypes recorded higher content of chlorophyll, total soluble sugar, total nitrogen and crude protein. The American cotton varieties AKH 09-5, GH-8001E and Suraj, American cotton hybrid Nirmal 996, desi cotton variety GA-8004 and desi cotton hybrid Namaskar_Gold-81 recorded comparatively higher yield and higher mean values for trichome density per cm2 and gossypol glands per cm2 and lower mean values for chlorophyll content, total soluble sugar, total nitrogen and crude protein under unprotected organic conditions which are desirable from pest tolerance point of view. The correlation studies revealed that, trichome density and gossypol glands had negative and significant correlation with aphids, leafhoppers and thrips but had positive and significant correlation with whitefly. Whereas, total soluble sugar, total nitrogen as well as crude protein had positive and significant correlation with aphids, leafhoppers and thrips but had negative significant correlation with whitefly. On the other hand, the bollworm damage had negative and significant correlation with trichome density. However, positive and significant correlation was also observed between the bollworm damage and chlorophyll content, total soluble sugar, total nitrogen and crude protein.ThesisItem Open Access Evaluation of parents and hybrids using Line x Tester analysis for seed yield and its components in safflower (Carthamus tinctorius L.).(Dr.Panjabrao Deshmukh Krish Vidyapeet,Akola, 2022-09-27) GARG, ARZOO.; Gawande, Dr. V. L.The present investigation was carried out to know the magnitude of heterosis, combining ability of parents and crosses for yield, its contributing traits and oil content. Thirty crosses [obtained by crossing two females (testers) with fifteen males (lines)], along with seventeen parents and three checks viz., PBNS 12, PKV Pink and A1 were evaluated in Randomized Block design during rabi 2019-20 with three replications at experimental field of Department of Agril. Botany, Dr.PDKV, Akola and observations were recorded for seed yield, yield contributing traits and oil content. Analysis of variance indicated presence of substantial genetic variability for the characters studied. The highest magnitude of heterosis over both standard checks and better parent for the traits days to 50 % flowering was noticed in AKS CMS 3A x GMU 2830 and in cross AKS CMS 3A x GMU 590 for days to maturity over mid and better parent. Maximum heterosis for seed yield per plant was exhibited by hybrid AKS CMS 3A x GMU 2273 over mid parent, over better parent and over standard check. Further, AKS CMS 2A x GMU 6891 exhibited significant average heterosis, heterobeltiosis for oil content. Whereas AKS CMS 2A x GMU 7573 exhibited maximum useful heterosis for oil content. The parents, GMU 590, GMU 2273 and GMU 589 among the lines and AKS CMS 3A among the testers were found to possess good GCA effects for seed yield and most of yield contributing characters. For oil content, GMU 7573, GMU 2273 and GMU 2830 among lines were best general combiners. These parents can be used in further breeding programme for improvement of concerned trait. The crosses AKS CMS 2A x GMU 1731 and AKS CMS 3A x GMU 7448 were good specific combinations for number of capsules per plant, and seed volume weight. Whereas, crosses AKS CMS 3A x GMU 2273, AKS CMS 2A x GMU 6891 were for seed yield per plant and seed filling percentage. Three promising crosses viz., AKS CMS 3A x GMU 2273, AKS CMS 3A x GMU 590 and AKS CMS 3A x GMU 589 identified on the basis of high mean, significant SCA effects and high heterosis over best check in desirable direction were detected. These crosses may be exploited for heterosis breeding and also for isolating desirable recombinants from advanced segregating generations (by using “B” line of CMS based testers along same male parent in concerned cross). Intermating plants from early segregating gnerations may be done to break undesirable linkages and to isolate desirable segregants for yield and contributing traits due to predominance of SCA variance.ThesisItem Open Access QUANTIFICATION OF RESISTANCE AND CHARACTERIZATION OF SOYBEAN GENOTYPES IN RESPONSE TO CHARCOAL ROT.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-06-10) CHAVAN, SNEHAL VINAY; Nandanwar, Dr. R.SThe present study entitled “Quantification of resistance and characterization of soybean genotypes in response to charcoal rot.” was carried out at Department of Agricultural Botany, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the year 2018-19 to evaluate various genotypes of soybean for charcoal rot resistance. Charcoal rot disease caused by Macrophomina phaseolina is one of the most damaging diseases of soybean resulting to 70 % losses and till date no immune genotype is known for the same. Various limitations inherent in field experiments may have hindered progress toward identifying new source(s) of resistance and breeding resistance in soybean. Non-field testing under semi-controlled conditions in a greenhouse or in controlled conditions in plant growth chambers may compliment or help to overcome the limitations of field-testing. The present investigation aimed to establish in-vitro screening procedure for screening of soybean for charcoal rot resistance and identify the resistant genotype(s). Fourteen core genotypes comprising popular varieties, newly released and mutant genotypes were screened under field and in-vitro conditions. The genotypes were screened under sick-plot during Kh-2018 and in-vitro screening was carried out using blotter-paper, pot-inoculation technique, stem cut inoculation, in-vitro on leaf technique using virulent pure culture of M.phaseolina. Disease infection was scored using the scales as per the experiment and genotypes were categorized accordingly. Four genotypes including varieties viz., AMS MB 5 -18, AMS MB 5-19, AMS 77 and AMS 1001 were identified as resistant to M phaseolina in all the in-vivo and in-vitro screening. Molecular characterization of these genotypes was done by using SSR and RGA markers. Molecular profiles revealed remarkable polymorphism and observations showed that in total 181 amplicons were tested with an average of 6.03 alleles per locus. Out of the total screened alleles 62 were monomorphic alleles with an average of 2.07 and 119 were polymorphic alleles with an average of 3.97. Results showed an average of 65.75 polymorphism percent. The PIC (Polymorphic information content) value of 30 microsatellite loci ranged from 0.29 to 0.83 with an average value of 0.69, these studies will help in mapping studies and breeding program for development of charcoal rot resistance in soybean genotypes which will be of utmost importance.ThesisItem Open Access STABILITY ANALYSIS OF CHICKPEA (Cicer arietinum L.) GENOTYPES UNDER DIFFERENT ENVIRONMENTS.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-07) PAWAR, KRUSHNAJI SHIVAJI.; Meshram, Dr. M. P.The present investigation entitled “Stability Analysis of Chickpea (Cicer arietinum L.) Genotypes Under Different Environments” was undertaken with view to estimate stability parameters for seed yield and its important components and to identify most stable genotype under different environments. Twenty genotypes were sown on four different sowing dates in a Randomized Block Design with two replications for measuring stability of genotypes for different characters. The data was subjected to statistical analysis as per Eberhart and Russell (1966) model. In general, genotypic differences were found significant for all character indicating the presence of genetic variability in the material. G x E interaction was found to be significant for the characters viz., days to first flower, days to 50% flowering, number of days to first pod initiation, primary branches per plant (No.), seeds per pod, seed yield (g/plant) and harvest index. Linear component of G X E interaction was found significant for the characters viz., days to first flower, days to 50% flowering, days to first pod initiation, Plant height (cm), primary branches per plant, days to maturity, seeds per pod and harvest index. The genotype JG-14 recorded average stability for days to first flower initiation. The genotype VIJAY recorded average stability for days to 50% flowering. The genotypes RVG-203 and PDKV-KANCHAN exhibited average stability for days to first pod initiation. The genotypes SAKI-9516, DIGVIJAY, PHULE G -0819-43, AKG-70, JG-14 and PKV HARITA recorded average stability for primary branches per plant. The genotype JAKI-9218, PDKV-KANCHAN, PHULE G-0819-43, BDNG-804, PHULE G-13107 and JG-14 recorded average stability for seeds per pod. The genotypes JAKI-9218, PDKV-KANCHAN, PHULE G-13107, PHULE G -0819-43, BDNG-804, JG-14 and PKV HARITA showed average stability for seed yield per plant (g). The genotypes PHULE G-13107, BDNG-804 and JG-14 showed average stability for harvest index. Under late sown irrigated condition, the genotypes JAKI-9218, PDKV-KANCHAN, PHULE G-13107, PHULE G-081943, BDNG-804, JG-14 and PKV HARITA recorded average stability for seed yield (g/plant) hence adaptable to all four types of environments. The genotypes AKG-70 showed above average stability for seed yield (g/plant). None of the genotype was found stable for all the characters under study.ThesisItem Open Access CHARACTER ASSOCIATION STUDIES ON BIOFORTIFIED WHEAT (Triticum aestivum L.).(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-24) WALAKE, OM BHAGWAN; Potdukhe, Dr. N. R.The present investigation entitled “Character association studies on biofortified wheat (Triticum aestivum L.)” was carried out during rabi season of the year 2017-2018 at the Wheat Research Unit, Dr. PDKV, Akola. The study was undertaken on thirty seven genotypes of biofortified wheat using randomized block design with four replications. The highest genotypic coefficient of variation as well as phenotypic coefficient of variation for biofortified wheat genotypes was observed for grain yield per plot and among the quality parameter observed for grain manganese content. Almost all characters exhibited high heritability (27% - 98%). Highest genetic advance was observed for the character straw yield per plot and grain yield per plot and among the quality parameter observed for grain manganese content. However, it was ranged from (0.48% - 548.06%) for all the characters. High estimate of genetic advance as percentage of mean was observed for the character grain yield per plot and among the quality parameters for grain manganese content. For biofortified wheat genotypes, genotypic correlation studies between yield contributing traits and quality parameter revealed that grain yield was closely associated with straw yield per plot, harvest index, grain weight per plant, 1000 grain weight, tillers per plant and flag leaf area. While, days to maturity, spikelets per spike and days to 50% heading exhibited negative but significant correlation with grain yield. Among the quality parameters, grain protein content exhibited positive and significant correlation with grain yield. Significant positive inter-correlation between the micronutrients was observed. Path coefficient analysis revealed positive direct effect on grain yield through harvest index, tillers per plant, spikelets per spike, days to maturity, 1000 grain weight, grains per spike, plant height and flag leaf area. Hence, these characters may be given consideration while formulating selection indices for the improvement of wheat. The direct effect of iron content on grain yield was found positive. This indicated that selection for higher micronutrient content will affect the yield in positive direction. In respect of quality parameters, out of thirty seven genotypes of biofortified wheat, the genotype MACS 6222 recorded highest grain protein content followed by AKAW 4210-6 and HD 3086. Maximum grain iron content recorded by DWAP 1722 followed by QBP-17-14 and BWL 6893. Maximum zinc content was recorded by GRU 1718-06 followed by HTW 63, HPBW 01 and MACS 6222. Similarly, more copper content by HD 3086, QBP-17-09, HPBW-01, WH 1202, MACS 6222 and manganese content by HD 3086, QBP-17-11, HPBW 01 and DWAP 1722. Thus, these above mentioned genotypes identified as micronutrient dense genotypes on the basis of results obtained from mean values of quality parameters and can be used for further quality improvement programme.ThesisItem Open Access GENETIC DIVERSITY AND CORRELATION STUDIES IN SAFFLOWER (CARTHAMUS TINCTORIUS L.)(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-08-21) DHAGE, PRIYANKA SAHEBRAO.; Ratnaparkhi, Dr. R. D.The investigation on "Genetic diversity and correlation studies in safflower (Carthamus tinctorius L.)” was undertaken to estimate the extent of diversity and to estimate the contribution of each character towards genetic diversity and to study association among yield and its components. The set of 63 genotypes along with three checks 'A-1, PBNS-12, PKV Pink' were evaluated in augemented block design with nine blocks at the field of Oilseeds Research Unit, Dr. PDKV, Akola during rabi 2018-2019. The data was recorded on the characters viz., days to 50% flowering, days to maturity, plant height (cm), number of branches per plant, number of capitula per plant, number of seeds per capitulum, volume weight (g/100ml), 100 seed weight (g), oil content (%) and seed yield per plant (g). Present study revealed that high genetic diversity was present for all the characters in the genotypes under study since the variation among the genotypes were significant for all the characters. It was observed that seed yield per plant (25.69%) contributed maxmimum towards genetic divergence followed by days to maturity (18.41%), days to 50% flowering (16.08%), number of seeds per capitulum (12.82%) and plant height (10.58). The 63 genotypes and three checks were grouped into ten clusters. The average inter cluster distance was maximum between clusters VI and VIII (3896.92), followed by clusters X and VIII (3096.12), clusters III and VI(2772.88), clusters II and VIII (2383.65), clusters V and IV (2296.31). Canonical analysis indicated that overall contribution of first four canonical roots was 72.202% suggesting completion of maximum portion of differentiation in the first four phases. This indicates that there was need to involve some more characters in the further to study maximum variation. The present study projected the importance of GMU-7363, GMU-5135, GMU-5134 as parents for earliness while parents GMU-7448, GMU-5136, GMU-2648, GMU-2928, GMU-667, GMU-1798, GMU-2830 and GMU-7355 for characters viz plant height, number of branch per plant, number of capitula per plant, number of seeds per capitulum, 100 seed weight, volume weight, oil content and seed yield per plant respectively for their further improvement in respect to yield contributing characters. On the basis of cluster means and maximum inter-cluster distance, potential crosses suggested for different traits are GMU-7590 x GMU-972 for high oil with earliness and high yield potential, GMU- 4914 x GMU-972 for earliness with moderate volume weight and high yield potential, GMU-590 x GMU-7590 for high plant height with high oil, GMU-2830 x GMU- 972 for high oil with earliness, GMU-3438 x GMU-4914 for high hundred seed weight with earliness, GMU-7590 x GMU-6852 for high plant height and high oil with earliness. Correlation studies revealed that, the seed yield per plant was significantly and positively correlated with plant height, number of branches per plant, number of capitula per plant, number of seeds per capitulum, 100 seed weight and volume weight.ThesisItem Open Access LINE X TESTER ANALYSIS FOR YIELD AND IT’S CONTRIBUTING TRAITS IN WHEAT UNDER HEAT STRESS CONDITION (Triticum aestivum L.)(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-08-22) BHALERAO, HARIDAS JALINDAR; Bharad, Dr. Swati G.The present study entitled “Line x Tester analysis for yield and it’s contributing traits in wheat under heat stress condition (Triticum aestivum L.)’’ was carried out with objectives to study the heterosis and combining ability effects in different genotypes of wheat using Line x Tester analysis. The crosses were made using six lines (females) viz. NIAW-34, AKW-1071, PDKV-Sardar, AKAW-4627, AKAW-4927, AKAW-5023 and eight testers (males) viz., AKW-2862-1, C-306, DHTW-60, WH-730, HTW-6, HINDI-62, AKAW-3717, HTW-11 and their 48 crosses along with the PDKV-Sardar as standard check have been evaluated in randomized block design with three replications at Wheat Research Unit, Dr. PDKV, Akola during rabi season of 2018-19. The resultant hybrids and parents were evaluated for days to heading, days to maturity, plant height (cm) at maturity, number of tillers per plant at maturity, spike length, grains per spike, grain weight per spike, 1000 grain weight, grain yield per plant, protein percent (%), β-carotene content (ppm). The highest significant sca effect for grain yield was recorded by the cross AKAW-5023 x WH-7304 followed by AKAW-4627 x C-306, AKAW-4627 x DHTW-60, AKW-1071 x AKW-2862-1, NIAW-34 x AKAW-3717. The crosses AKW-1071 x HTW-11 and PDKV-Sardar x HINDI-62 recorded highly significant sca effects for protein percent and β-carotene content respectively. These crosses also recorded the sca effects for most of the yield contributing traits. From the present study, it is concluded that genotype AKAW-4627 x C-306, AKAW-4627 x DHTW-60 and AKAW-4927 x DHTW-60 are identified as best combiners for yield and yield contributing traits. Among the parents two lines (AKAW-4627 and AKAW-4927) and two testers (C-306 and DHTW-60) 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. On the basis of mean yield performance, standard heterosis, gca and sca effects three crosses were identified as promising crosses which are viz., AKAW-4627 x C-306, AKAW-4627 x DHTW-60, AKAW-4927 x DHTW-60 and AKAW-4627 x WH-730 should be exploited for getting useful segregants in further generation for development of genotypes suitable for heat tolerance condition. The genotypes C-306 was identified as best combiner followed by AKW-1071, WH-730, AKAW-4927 and AKW-2862-1 days to heading, plant height, number of tillers per plant, number of seeds per spike, grain weight per spike,1000 seed weight and grain yield per plant hence, should be used as one of the parents for crossing with above suggested genotypes for getting better recombinants in further segregating generations for development of genotypes with high yield and suitable under the heat stress condition.ThesisItem Open Access PHYSIOLOGICAL EVALUATION OF COTTON GENOTYPES FOR MOISTURE STRESS.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-08-05) SONONE, MADHAVI PRAKASH.; Rathod, D. T. H.The present investigation entitled “Physiological evaluation of cotton genotypes for moisture stress” was conducted during kharif season of 2018-19 in RBD on the experimental field of Cotton Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.) under non stress and water stress condition. The seeds of ten cotton (Gossypium hirsutum) genotypes i.e. AKH-09-5, AKH-2012-8, AKH-1301, AKH-1302, NH-545, P-688, AKH-9916, AKH-88 28, PKV Rajat and NH-615 were sown in three replications. One set of three replications grown in field condition and another set of genotypes replicated thrice was sown in earthen pots under rainout shelter. Present investigation indicates, significant superiority of the cotton genotypes tolerant towards water stress on the basis of morpho-physiological, biochemical, stress indices, seed cotton yield and its attributes. Leaf area (cm2/ plant) was remained significantly higher in AKH-9916 under both stress (1030.04 cm2/ plant) and non-stress condition (1965.44 cm2/ plant) at 120 DAS. Genotype AKH-9916 also recorded significantly higher total dry matter production at harvest under both non stress (58.2 gm/plant) and water stress condition (33.53 gm/plant). Relative water content percentage was recorded significantly higher in genotype AKH-1301 (79.36 %) under non stress condition where in stress condition, it was found lower as compared to genotypes under non stress condition. AKH-9916 (70.86 %) was recorded higher in respect of relative water content percentage in water stress condition at 120 DAS. Significantly more proline content was observed in AKH-09-5 (65.03 µg/g fresh weight) under non stress condition and AKH-1301 (81.8 µg/g fresh weight) in stress condition at 120 DAS. On the basis of stress indices higher yield stability index (0.72) and higher drought tolerant efficiency (73.1 %) was observed in PKV Rajat followed by AKH-9916 and AKH-8828, the released genotype. Under non stress condition AKH-9916 (50.53 g/ plant) was recorded significantly more seed cotton yield followed by NH-615 (49.80 g/plant), AKH-1302 (49.23 g/plant) and AKH-8828 (48.66 g/plant). Under water stress condition, AKH-9916 (36.36 g/plant) was remained significantly higher followed by AKH-8828 (34.86 g/plant) and AKH-1301 (31.63 g/plant) for seed cotton yield. The genotype AKH-1302 (49.23 g/plant) produce statistically more seed cotton yield than the released variety PKV Rajat (40.84 g/plant) followed by AKH-1301 (47.13 g/plant) under non stress condition. Under water stress condition none of the new genotypes recorded statistically more seed cotton yield than the released varieties i.e. AKH-9916, AKH-8828, PKV Rajat and NH-615. The present study projected the significant superiority of cotton genotypes AKH-9916, AKH-8828 and AKH-1301 tolerant towards water stress when sown under stress and non-stress condition. However, the present findings needs further confirmation on multilocation basis.ThesisItem Open Access GENETIC VARIABILITY AND STABILITY ANALYSIS FOR YIELD AND ITS CONTRIBUTING TRAITS IN CHICKPEA (Cicer arietinum L.)(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-08-23) BANKAR, SACHIN GOVINDRAO; Vaidya, Dr. E. R.The present investigation entitled “Genetic variability and stability analysis for yield and its contributing traits in chickpea (Cicer arietinum L.)’’ was undertaken with view to estimate extent of genetic variability among the chickpea genotypes and estimate stability for yield and its components. Twenty genotypes were sown on three different environments (Akola, Buldana, Nagpur) in a Randomized Block Design, with three replications for measuring stability of genotypes for different characters. The data was subjected to statistical analysis as per Eberhart and Russell (1966) model. The ANOVA reveled highly significant difference among the all genotypes for all the characters studied indicating the presence of substantial amount of genetic variability. The character number of pods per plant showed medium GCV (14.88%) accompanying with medium broad sense heritability (47.70%) and higher expected genetic advance (21.17%) values indicating thereby amount of variation in aforesaid character. The higher magnitude of PCV as compared to GCV in respect of characters, number of pods per plant, seed yield per plant, indicated the greater effect of environment on these characters. The high heritability estimate was showed in protein content (89%) followed by medium heritability (40-60%) for the characters 100 seed weight (49.90%), number of pods per plant (47.70%) and number of seeds per pod (47%). This indicated that these characters are may be governed by non-additive component of variation which is non fixable, heterosis breeding can be fruitfully exploited in improving these characters. The character seed yield per plant and number of secondary branches per plant showed medium GCV (12.24 and 10.73) accompanying with medium heritability (37.30 and 37.40) and medium expected genetic advance (15.41 and 13.53). The character days to maturity showed low GCV (1.63%) accompanying with low heritability (20%) and low expected genetic advance (1.51%). In general, genotypic variances were found significant for, days to 50% flowering, plant height, number of primary branches per plant, number of secondary branches per plant, number of pods per plant, number of seeds per pod, 100 seed weight, seed yield per plant and protein content, except days to maturity when tested against G X E interaction. Environmental variance was significant for all the studied characters except days to 50% flowering, protein content. Genotype x environmental interactions was non-significant for all the traits. Linear components of G X E interaction was found significant for the characters viz., days to 50% flowering and 100 seed weight (g) whereas pooled deviation (non-linear component) was found significant for the traits viz., days to maturity, number of secondary branches per plant, number of pods per plant, number of seeds per pod, seed yield per plant. Environment (linear) effects were also significant for all the studied characters except protein content. The most of genotypes showing wider adaptability for different characters studied viz., AKG-1303, AKG-1401, Phule G-0405 and BDNG-797 recorded average stability for days to 50 % flowering. The genotypes AKG-1303, AKG-1401, BDNG 2015-9, Phule G-0819-43, Phule G-15109, Phule Vikram and JAKI-9218 recorded average stability for plant height.
