Genetic Variability for Yield and Yield Attributing Characters in Moong Bean (Vigna radiata L. Wilczek)

The present investigation entitled "Genetic Variability for Yield and Yield Attributing Characters in Moong Bean (Vigna radiata L. Wilczek)" was conducted to estimate the extent of genetic variability, heritability, and genetic advance among different yield and yield-related traits. Thirty genotypes of moong bean were evaluated during Kharif season 2024 at the Research Farm, Department of Genetics and Plant Breeding, Tantia University, Sriganganagar, Rajasthan, using a randomized block design with three replications. The observations were recorded for ten characters—days to 50% flowering, days to maturity, plant height, number of branches per plant, number of clusters per plant, number of pods per plant, pod length, number of seeds per pod, 100-seed weight, and seed yield per plant. The analysis of variance revealed significant differences among genotypes for all traits, indicating the presence of sufficient genetic variability. High heritability coupled with high genetic advance was observed for the number of pods per plant, 100-seed weight, and seed yield per plant, suggesting the predominance of additive gene action and the scope for selection-based improvement. Moderate heritability and genetic advance were observed for days to maturity and pod length. The results indicated that traits such as pods per plant, branches per plant, and 100-seed weight are major contributors to yield and should be emphasized during selection for yield improvement in moong bean breeding programs.
