Genetic divergence among greengram (Vigna radiata (L.) Wilczek) germplasm collections

Abstract

Four hundred and forty five genotypes of greengram were evaluated for eight quantitative traits viz. plant height, number of branches/plant, number of clusters/plant, number of pods /clusters, number of pods/plant, pod length, 100- seed weight and seed yield /plant. The data was subjected to cluster analysis, and the genotypes were grouped under three discrete clusters. This study concluded that an effective hybridization programme including the genotypes between the clusters I, II and III would produce wider segregation that might be used for development of improved greengram varieties.
