Abstract

Genetic Variability Studies for Yield Attributes in Mungbean (Vigna radiata L. Wilczek) were conducted on 15 Mung bean genotypes at Horticulture Research Farm, SGT, Gurugram, Haryana during kharif 2021. The study was set up in a Randomised Block Design with three replications and focused on variability of 16 morpho-physiological characters. The analysis of variance revealed extremely significant variations across accessions for all characteristics. There is potential for improvement in traits with high mean and high range, such as Days to 50% blooming, Days to initial flower opening, Days to cessation of flower, Relative water content, Biological Yield, Harvest Index, and Grain yield per plant. IPM205-7 demonstrated advantage in terms of early blooming as well as a number of yield- related features like height of the plant, number of secondary and primary branches per plant, number of pods, root length, and number of roots, biological yield, harvest index, and grain yield per plant.
