Genetic Variability Analysis for Seed Yield and its Components in Mungbean (Vigna radiata L. Wilczek)

Abstract

Sixty four powdery mildew disease tolerant genotypes of mungbean were grown under All India Coordinated Research Project on Mullarp, during kharif, 2004 and rabi, 2004-05 in randomized complete block design with three replication to compare their performance, existing variability among various yield related traits. Analysis of variance showed significant variation for days to 50% flowering, days to maturity, plant height, number of primary branches plantG 1 , number of clusters plantG 1 , number of pods clusterG 1 , pod length, number of seeds podG 1 , number of pods plantG 1 , 100 seed weight, hard seed percent, protein content, phenol content and seed yield plantG 1 . High heritability coupled with high genetic advance as percentage of mean was observed for seed yield plantG 1 , number of primary branches, number of clusters plantG 1 and plant height. Direct selection for the traits possessing additive genetic variance, which is fixable in nature, may lead to development of desirable mungbean plant.
