dc.description.abstractThe present research programme entitled “Divergence and Cause-Effect Relationship in Kabuli Chickpea (Cicer arietinum L.) Genotypes” was conducted with thirty Kabuli Chickpea genotypes collected from various places across the country at the research farm, TCA, Dholi, Muzaffarpur, Bihar during the Rabi season of 2020-21. The material was assessed using RBD (Randomized Block Design) with three replications. Fifteen traits were selected for the study viz., Plant height (cm), days to 50% flowering, number of primary branches per plant, number of secondary branches per plant, days to pod initiation, number of effective pods per plant, number of seeds per pod, number of nodules per plant, nodule fresh weight (g), nodule dry weight (g), 100 seed weight (g), harvest index (%), relative water content (%), membrane stability index (%) and grain yield per plant (g). ANOVA exhibited significant Mean Sum of Square (MSS) values due to genotype for all traits, which is indicative of the presence of ample amount of variability in the Kabuli chickpea genotypes used for the study. The Phenotypic Coefficient of Variance (PCV) values was slightly greater than the Genotypic Coefficient of Variance (GCV) values which was attributed to the meager effect of environment on the morphological appearance of the traits. In the study, high heritability coupled with high genetic advance was observed for plant height, number of effective pods per plant, number of seeds per pod, number of nodules per plant, nodule fresh weight, nodule dry weight, 100 seed weight, harvest index and grain yield per plant, which indicated the preponderance of additive gene action. Therefore, response to early selection may be effective in improving these traits. Based on correlation and path analysis, number of effective pods per plant, number of seeds per pod and harvest index exhibited positive and significant correlation with grain yield per plant having their positive direct effect suggesting that during selection these traits may be considered as a prime trait to improve yield of kabuli chickpea. Based on diversity using Tocher's method, the thirty genotypes were grouped into six different clusters. The inter-cluster distances were recorded higher than the intra-cluster distances further indicating a considerable amount of diversity in the genotypes involved. Highest inter-cluster distance was found between cluster III and VI followed by cluster I and VI. Among all the characters studied, 100 seed weight contributed maximum to the diversity. Further, genotypes ICCV 191307 (cluster III) and ICCV 191326 (cluster VI) were selected as superior lines based on high inter cluster distance alongside mean performance for most of yield attributing traits suggesting that these genotypes may be used in crossing programme to obtain heterotic recombinants as well as transgressive segregants.en_US
