Variability, Heritability and Genetic advance Studies of Mungbean Genotypes (Vigna radiata L.) at Satna District of Madhya Predesh (India)

Abstract

Seventeen diverse cultivars of mungbean grown in Completely Randomized Block Design (CRBD) at AKS University, Satna, during Kharif season on July 2021. Data were collected for thirteen quantitative traits and estimated for variance, genetic variability, heritability and genetic advance. The design of the experiment indicated highly significant differences for all the characters due to treatments. The analysis of variance indicated the existence of sufficient amount of variability among genotypes for all the studied characters. The highest GCV and PCV were observed for no. of pods/clusters followed by biological yield (g), seed yield/plant (g), no. of primary branches/plants, number of clusters/plants and no. of pods/plants. Higher estimates (h2b) >80% were observed 1000 seed weight followed by no. of seed/pods, days to maturity, days to 1st flowering, pod length, seed yield/plant, and no. of pods/clusters. High heritability coupled with high genetic advance observed for 1000 seed weight, biological yield, days to maturity, days to 1st flowering, days to 50% flowering and seed yield per plant indicating that these characters could be prominently governed by additive gene action. So the selection of these traits could be more effective for desired genetic improvement.
