Medik]” At the Crop Research Center of the Sardar Vallabhbhai Patel University of Agriculture and Technology Meerut, experiments were carried out to measure the genetic variability using 29 genotypes with three replications on various Rabi 2021 sowing dates. All traits under examination have a sizable degree of variability, according to the analysis of variance. For biological yield, high GCV and PCV were noted. Number of pods per plant, biological yield per plant, seed yield per plant, days to 50% flowering, number of branches per plant, harvest index, 100 seed weight, plant height, days to maturity, and number of seeds per pod were all associated with high genetic makeup. The number of branches per plant showed significant heritability together with strong genetic progress, indicating that direct selection for this characteristic may be advantageous and that heredity may be caused by additive gene effects. In all the studied traits, the magnitude of the genotypic correlation coefficients was greater than the phenotypic correlation coefficients. At both the genotypic and phenotypic levels, seed yield exhibited a positive and highly significant connection with plant height, the number of branches per plant, the number of pods per plant, biological yield, and harvest index. Path coefficient study revealed that among the numerous yield-contributing variables, biological yield, harvest index, and seed yield per plant were all directly related to seed yield and measured in days to 50% flowering. Selection based on these traits may increase grain yield per plant. D2 analysis with ten component characters produced four clusters. The two largest clusters, II and IV, included a total of 9 genotypes, making them the four clusters. Cluster III had three genotypes, while Custer I had eight. Cluster III experienced the most intra-cluster distance, whereas cluster IV experienced the smallest intra-cluster distance. Cluster I and Cluster III had the greatest intercluster distance, whereas Cluster II and Cluster IV had the smallest intercluster distance. Numerous genotypes that at the morphological level were dispersed in various groups suggested a higher level of genetic diversity. (Atar Singh) (Anant) (Advisor) (Author)EnglishThesis
