The present investigation entitled “Estimation of combining ability effect in mungbean (Vigna radiata (L.) Wilczek) was carried out at College of Agricultural, Kharpudi, during kharif 2016 and 2017. The material for the present investigation comprised ten parents BPMR 182, BPMR 132, BPMR 21, BPMR 126, BPMR 75 and BPMR 38. Four varieties as females are BM 2002-1, BM 4, JL 781 and AKM 4. Were crossed in Line x Tester fashion to estimate the combining ability for yield and yield attributing traits in mungbean. Analysis of variance revealed significant differences among genotypes, crosses, lines, testers and line x tester interactions for most of the traits. Preponderance of non-additive gene effects was realized from higher values of specific combining ability compared to general combining ability and ratio of variances of SCA to GCA. The parents showed high GCA can be used for the future hybridization programmes. The gca estimates of lines and testers emphasized the importance of lines BM 2002-1, JL 781 and tester BPMR 126, BPMR 75for their use as a desirable parents for enhancing the yield potential through assembling the favorable genes for yield and yield components. The crosses which showed high SCA effect could be used for the hybrid development. The high yielding crosses viz., BM 2002-1 X BPMR 126, BM 2002-1 X BPMR 75, BM 4 X BPMR 75, JL 781 X BPMR 132, JL 781 X BPMR 126 and JL 781 X BPMR 75 were found to be the superior for seed yield and yield component and should be further tested across the different environment for their stability performance.
