Assessment of genetic diversity in mungbean (Vigna radiata L)

An experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to analyze the genetic diversity of fourteen mungbean genotypes through Mahalanobis D2 statistic and principal component analysis for nine quantitative traits related to yield. Based on the results of this study the genotypes were grouped into four clusters by diversity (D2) analysis where cluster IV comprised six genotypes, cluster I had four genotypes and cluster II and III had 2 genotypes in each. The maximum inter-varietal distance was observed between G1 and G6 (1.288). Genetic diversity in mungbean can be explained 89.82% by the first four components, according to principal component analysis. G1 (BARI mung1), G2 (BARI mung2), G6 (BARI mung6), G7 (BARI mung7) and G10(BINA moog-5) were shown to have potential for further hybridization in breeding programs, based on group distance and other agronomic performance measures.
