Assessment of Genetic Diversity in Green Gram [Vigna radiata (l.) Wilczek] for Quantitative and Qualitative Traits

Abstract

The current study, "Assessment of genetic diversity in green gram [Vigna radiata (L.) Wilczek] for quantitative and qualitative traits" was carried out during the kharif of 2022 at the College of Agriculture, Dhule. The experimental materials consisted local collection of 42 mungbean genotypes which were evaluated in a randomized block design (RBD) with two replications, representing various eco-geographic regions for twelve different characters and studies of genetic divergence were carried out. The genetic diversity among landraces is determined by the range of D2 values which varied from 44.68 (MG-2022-15 and MG-2022-30) to 1678.53 (MG-2022-18 and MG-2022-31) for each genotype, showing adequate variance. Based on D2 levels, the 42 genotypes were split up into 16 groups with notable genetic differences. Cluster I and III were the largest, with 11 and 10 genotypes each. It was adjacent to Clusters II, which had eight genotypes. Based on inter-cluster means and per se performance, breeding programs may employ the following effective genotypes viz., MG-2022-31, MG-2022-42, MG-2022-21, MG-2022-40, MG-2022-39, MG-2022-14, MG-2022-11, MG-2022-18, MG-2022-02, MG-2022-25, and MG-2022-24 to further enhance grain yield and its contributing characters in mungbean.
