Genetic Diversity Analysis for Yield and Yield Attributing Triats in Chickpea (Cicer arietinum L.)

The present investigation on Genetic diversity analysis were studied in a set of 30 genotypes of Chick pea (Cicer arietinum L.) using Mahalanobis D2 Statistics, at field experimentation centre of Department of Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, U. P. The experiment was conducted during rabi 2020 - 21 in a randomized block design with three replications. Observations on five randomly selected plants were recorded for days to fifty percent flowering, days to maturity, plant height (cm), primary branches per plant, secondary branches per plant, total number of pods per plant, total number of effective pods per plant, biological yield per plant (gm), 100 - seed weight (gm), harvest index (%) and seed yield per plant. The cluster I and cluster VI was with the highest number of genotypes (8) followed by cluster V (06), clusters VI (04), cluster II (03) cluster III had single genotype. Inter cluster values varied from 5.47 to 16.01. However, the maximum inter - cluster distance was noticed between clusters VI (16.01), followed by cluster V (11.83), cluster IV (11.57), cluster I (5.47) and Cluster II (4.19). Whereas, seed yield per plant contributed highest (20%), followed by harvest index (15%), number of effective pods per plant (14%), 100 seed weight (12%), Biological yield per plant (10 %) to the divergence, followed by total number of pods per plant (10%), number of secondary branches (8%), number of primary branches (5%), Plant height (3%), days to maturity (2%) and days to 50% flowering (1.15%) contributed maximum towards diversity. Based on inter cluster distances and Per se performance ICC 11334, ICC 4568, ICC 11163, ICC 6058, ICC 5138, ICC 6058, ICC 7365A were identified for inclusion in hybridization programme for realizing desirable transgressive segregates.
