Evaluation of Greengram (Vigna radiata L.) Germplasm for Seed Yield and Yield Related Traits through Cluster Analysis

An investigation was conducted at the Agricultural Research Station, Madhira during rabi, 2017-18 to study genetic divergence and clustering pattern among 39 greengram germplasm accessions in Randomized Block Design (RBD) replicated twice for eight quantitative traits. Principal component analysis revealed that first three principal components-PC I, PC II, III—contributed about 83.95% of variation understudied genotypes. According a cluster analysis, genotypes can be divided into seven different groups, with I being largest maximum 27 Cluster III is second 5 genotypes, II third 3 The mono genotypic indicated by IC-436634, IC-426458, IC-261272 WGG-42 indicates presence diversity generating variability through hybridization. distance inside 54.11, while greatest between clusters IV VII 507.95. Data on means various traits VI had highest mean value number per plant, pods seeds produced plant. total considerably influenced both plant height quantity features Plant made contribution (27.25%) smallest (20.23%) diversity. For purpose retrieving superior recombinants segregating generations, inter may included hybridization programme.
