Genetics Analysis of Yield and Its Component Traits in Mungbean (Vigna Radiata L.Wilczek)

The combining ability of 30 hybrids between 10 lines and 3 testers evaluated with parents in mungbean revealed significant role of additive and non-additive gene actions, the former being predominant for number of branches per plant and 100-seed weight, and the later for plant height, number of pods/plant, number of seeds/plant and grain yield/plant. Good combining parents for different characters could be identified for use as a favourable source of gene (s) to effect improvement in specific traits. Seven cross combinations for plant height, six for number of branches, six for number of pods/plant, 4 for number of grains/pod and 12 each for 100-grain weight and 10 for grain yield per plant exhibited significant specific combining ability effect. Number of branches per plant can be improved by pedigree selection.
