ThesisItem Open Access GENETIC STUDIES IN AJWAIN (Trachyspermum ammi L.).(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2021-10-13) MORE, HITAISHI SUDHIR.; Ujjainkar, Dr. V. V.The present investigation entitled “Genetic Studies in Ajwain (Trachyspermum ammi L.)’’ was carried out with twenty-six genotypes. The experiment was conducted in Randomized Block Design with three replications during Rabi 2020-2021 at Chilli and Vegetable Research Unit Dr. PDKV, Akola. The observations were recorded on five randomly selected plants, from each genotype in each replication. The thirteen characters studied were days to first flowering, days to 50 per cent flowering, days to maturity, plant height at maturity, number of primary branches per plant, length of first internode, number of umbels per plant, number of umbellate per umbel, number of seeds per umbel, number of seeds per umbellate, diameter of main umbel, test weight and seed yield per plant. The data so obtained was subjected to analysis of variance, correlation studies and path analysis. Genotypes, PDKV AJ 11, PDKV AJ 10, PDKV AJ 16, PDKV AJ 06, PDKV AJ 04, PDKV AJ 09, PDKV AJ 20, PDKV AJ 12, AA-19-01, PDKV AJ 18, PKV-07AA-2 and PDKV AJ 22 found high potential for seed yield, whereas PDKV AJ 14, PDKV AJ 19, PDKV AJ 02, PDKV AJ 04, PDKV AJ 18, PDKV AJ 20 were the early maturing genotypes. Analysis of variance indicated significant differences among the genotypes for all the traits under study. The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV). The high values of GCV and PCV observed for days to first flowering, days to 50 per cent flowering, days to maturity, plant height at maturity, number of primary branches per plant, length of first internode, number of umbels per plant, number of umbellate per umbel, number of seeds per umbel, number of seeds per umbellate, diameter of main umbel, test weight and seed yield per plant. High heritability was observed for test weight followed by number of umbels per plant, seed yield per plant, days to first flowering, number of seeds per umbel, number of umbellate per umbel and days to 50 per cent flowering. High genetic advance was observed for number of seeds per umbel, number of umbels per plant, days to first flowering and plant height at maturity. Seed yield per plant was significant and positively correlated with days to first flowering, days to 50 per cent flowering, days to maturity, plant height at maturity, number of primary branches per plant, number of umbels per plant and number of umbellate per umbel. The path coefficient analysis revealed that days to 50 per cent flowering, number of primary branches, length of first internode, number of umbels per plant, number of umbellate per umbel, number of seeds per umbellate and test weight showed positive direct effect on seed yield per plant. Hence, these characters may be given consideration while formulating selection indices for the improvement programme in ajwain.ThesisItem Open Access GENETIC DIVERGENCE STUDIES IN AMERICAN COTTON (Gossypium hirsutum L.)(2021-09-20) WANKAR, AKSHAY DNYANDEO.; DESHMUKH, Dr. D. T.A study “GENETIC DIVERGENCE STUDIES IN AMERICAN COTTON (Gossypium hirsutum L.)” was undertaken to estimate the degree of divergence among the forty genotypes of upland cotton using multivariate Mahalanobis D2 statistics at Cotton Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The analysis of variance revealed significant differences among forty genotypes for all eleven characters. This is also confirmed by Wilk’s criterion. The canonical analysis revealed that about 78.09 per cent of the total variation was accounted by the first five canonical roots. In vector I, halo length was important sources of variation. Whereas days to 50 per cent flowering was important sources of variation in vector II. In vector III, days to 50 per cent boll bursting, in vector IV days to 50 per cent boll bursting, in vector V, Boll weight played important role in genetic variation. seed cotton yield per plant, halo length, number of bolls per plant and ginning percentage were contributing towards genetic divergence. By using Tocher’s method, all forty genotypes were grouped into five clusters. Cluster I had highest number of genotypes (21) followed by cluster II (15), cluster V (2) and cluster III and IV represented by single genotypes. The maximum inter cluster distance was observed between cluster V and cluster II (D = 9.33). Hence the genotypes occured in cluster V and II may be utilized in breeding programme to get more heterosis for yield and yield contributing traits viz. number of bolls per plant, boll weight, seed index, seed cotton yield per plant, days to 50 per cent flowering and days to 50 per cent boll bursting. These cross combinations may also yield good transgressive segregants.ThesisItem Open Access EVALUATION OF ORGANICALLY GROWN COTTON GENOTYPES FOR INSECT PESTS TOLERANCE.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2021-08-21) AHERKAR, SHRADHA SHRIKANT.; Deshmukh, Dr. S. B.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 SODIUM AZIDE INDUCED GENETIC VARIABILITY IN M4 GENERATION OF INDIAN MUSTARD (Brassica juncea) coss.(Dr. Punjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-06-26) PRAJAPATI, SHAILENDRA SAGAR.; Nair, Dr. BeenaThe present study was carried out with the objectives to estimate variances between family and within family in M4 generation, to estimate genetic parameters in M4 generation and to identify superior mutants in M4 generation for further utilization, at experimental farm of AICRP Linseed and Mustard, College of Agriculture Nagpur during rabi 2019 in M4 generation. In rabi 2019, 161 mutants along with three checks (PM 21, Kranti and Shatabdi) were evaluated in M4 generation in two replication. Data were recorded on days to 50% flowering, days to maturity, plant height, number of primary branches plant-1, number of siliqua plant-1, number of seed siliqua-1, length of siliqua, seed yield plant-1 and 1000 seed weight were recorded. Analysis of variance indicated that the mean squares due to between family were highly significant for all traits, revealing the presence of significant genetic variability between the families. Intra class correlation (t) lead the conclusion that differences between individuals within family is large and each family differentiated distinctly from the other one at lower level in M4 generation hence, equal weightage to σ2f and σ2w were suggested to be considered for selection in M4¬ generation. The genetic parameter analysis revealed the importance of number of siliqua plant-1 and seed yield plant-1 for selection of better individual mutant from the progenies, based on genotypic coefficient of variation, phenotypic coefficient of variation, heritability and genetic advance. In M5 generation 93 individual plants from progeny were selected from 161 mutants of M4 generation. These mutants will be further evaluated in M5 generation and those found superior will be forwarded to yield trials.ThesisItem Open Access GENETIC VARIABILITY STUDIES IN M5 GENERATION OF MUSTARD.(Dr. Punjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-07-31) HOSUR, PRAKASH LAXMAPPA.; Nair, Dr. B.The present study was conducted with the objectives to estimate genetic variability of the selected mutants based on morphological characters and selection of superior mutants from M5 generation of mustard at AICRP on Linseed and Mustard farm of College of Agriculture Nagpur during rabi 2018 in M5 generation. In rabi2018, 26 advanced mutants along with four checks (Bio 902, Pusa bold, Kranti, Shatabdi) were evaluated in randomized block design in three replication. Data were recorded on days to 50% flowering, days to maturity, plant height, number of primary branches plant-1, number of siliqua plant-1, number of seeds siliqua-1, length of siliqua, seed yield plant-1 and 1000 seed weight. Diversity analysis of 10 high yielding advanced mutants was also done using 20 SSR primers. Analysis of variance indicated that the mean square due to between family and within family were highly significant for all traits, revealing the presence of significant genetic variability between the families. Intra class correlation (t) lead the conclusion that each family distinctly differentiated from each other and differences between individuals within a family is large for all the characters. Therefore it was suggested to assign more weightage to σ2f than σ2w for selection in this generation. The genetic parameter analysis revealed the importance of number of siliqua plant-1 and seed yield plant-1 for selection of better individual mutant from the progenies, based on genotypic coefficient of variation, phenotypic coefficient of variation, heritability and genetic advance. In M5 generation 8 high yielding plants from 26 advanced mutants were selected. Twenty SSR primers were used to evaluate 10 mutant genotypes of mustard. The PCR amplified products of each primer were resolved on 3% agarose gel electrophoresis. Out of 20 SSR primers screened during present study, 12 primers viz.,Na14E08, Na10G10, OI11B05, OI12E03, OI10F06, Ni4H05, Ni2E12, Ni2H06, Ni2Co1, Ni4G09b, Ra2DO4 and OI10F09were found monomorphic and eight primers viz., Na12E01, Na10E02, OI10E05, Na12A08, Na12D04, Na12F11, Ra2E12 and Ra2A11 were found polymorphic for the set of selected genotypes. And based on banding pattern dendrogram was generated for better understanding of the diversity among the selected mutants. Eight mutants viz., ACNMM 20, ACNMM 23, ACNMM 17, ACNMM 12, ACNMM 22, ACNMM 1, ACNMM 3 and ACNMM 9 were selected on the basis of yield and some of these mutants viz., ACNMM 23, ACNMM 22, ACNMM 13, ACNMM 14, ACNMM 7 were observed to be diverse from the checks as they appeared in different clades as that of checks. Some of them were found similar to the checks viz., ACNMM 9, ACNMM 4, ACNMM 17, ACNMM 19 to BIO-902 and ACNMM 15 to Kranti as they occupied the same clade as that of the check. These superior mutants will be further evaluated in multilocation trials of superior and diverse genotypes which can be released as variety or used in breeding programme.ThesisItem Open Access HETEROSIS AND COMBINING ABILITY ANALYSIS FOR YIELD AND ITS COMPONENT TRAITS IN MAIZE (Zea mays L.)(Dr. Punjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-08-05) CHAVAN, PAVAN BALIRAM.; Moon, Shri. M. K.Thirty F1 crosses were developed from six parents through full diallel mating design was evaluated for ten characters to estimate magnitude of heterosis and combining ability effect of parents, specific combining ability and reciprocal combining ability effect of crosses and to identify potential F1’s for advancing in further. Six parents and thirty crosses along with two checks Maharaja and Rajarshi were raised in adjacent plot in RBD replicated twice with spacing of 60 X 20 cm and recorded observation on days to 50% tasseling, days to 50% silking, days to maturity, plant height (cm), cob length (cm), cob girth (cm), number of grains cob-1, 100 grain weight (g), grain yield plant-1 and grain yield plot-1. All the crosses exhibited significant heterosis in positive and negative direction. The means squares due to general combining ability and specific combining ability were significant for all the characters and means squares due to reciprocal combining ability significant for all the characters except days to 50% tasseling and cob girth. CM145, CM152 and CM123 are the parents were identified as good general combiner for yield and other yield contributing characters. These genotypes were may be recommended for their use in the crossing programme or for developing gene pool. High mean performance, significant useful heterosis, in desirable direction and positive significance sca/rca effect were considered as the criteria for selection of potential crosses. Based on above criteria the crosses UMI1200 X CM152, CM152 X CM145, CM152 X UMI1200 and UMI1200 X CM124 were identified to exhibit high mean, significant positive heterosis over both the checks and significant positive combining ability for grain yield plant-1 and other yield contributing characters.
