Abstract: Mungbean holds significant importance as a pulse crop across Asia that run out with high high-quality protein (25%) and remarkable increase in quantity of thiamine, niacin, lysine and ascorbic acid during sprouting. Thus, breeding for developing mungbean genotypes with enhanced yield potential is paramount for maintaining mungbean productivity and safeguarding global food security.This study was performed for the mungbean crop at Agricultural Research Station, Badnapur during Kharif 2022-23 with an aim to estimate the genetic effects influencing yield and yield related traits in 54 mungbean crosses derived from mating six females and nine males in line × tester mating system. The results manifested that genotypes were highly significantly for all the yield and its contributing characters. Significant variations were also predicted among the lines, testers and line × tester for all the studied traits. The dominance variance (s²D) was in greater amount as compared to the additive variance (s²A) for most of the traits. Formerly, the value of s² SCA variance was notably more than the value of s²GCA variance for all the traits which exerted non additive gene effects for substantial influence on the genetic manifestation of the studied traits. Therefore, it is advised that hybridization be pursued for characteristics influenced by non-additive genetic effect, followed by selection in later generations in mungbean.
