Mungbean (Vigna radiata (L.) Wilczek) is having a desirable characters like short duration, high protein, less anti nutritional factors, nitrogen fixing capacity, suitable for inter cropping, making many kinds of foods for higher human consumption and cosmetics products and some of the undesirable characters like low yield, low test weight. The aim of the study is to check crossabil;ity of Vigna radiata with all wild Vigna species and to create variability through wide hybridization and to develop superior segregants for yield component coupled with pest and disease resistance. The interspecific crosses were attempted with thirteen wild relatives of mungbean (V. radiata) were employed with V. radiata as male parent. The highest pod set of 25 and crossability of 21.92 per cent was recorded by the cross V. radiata x V. radiata var. sublobata and lowest pod set of 2.0 per cent recorded by the cross V. radiata x V. dalzelliana in the direct cross combinations. The highest pollen germination 69.72 per cent was recorded by V. radiata x V. radiata var. sublobata. The estimates of pollen fertility was sufficient enough to recover F2 segregants in all the crosses combination. For all the traits in majority of the crosses, In the F2 generation the skewness was positive indicating that predominance of dominant alleles. Among the direct crosses V. radiata x V. mungo var. silvestris exhibited highest value for four characters viz., number of clusters per branch, number of clusters per plant, number of pods per plant and single plant yield. The cross V. umbellata x V. radiata showed better performance for the characters viz., number of branches and number of clusters in reciprocal direction In advanced generation of Vigna radiata x Vigna umbellata cross combination has expressed virus resistance for nine seasons. The same line was tested by agro inoculation for confirmation of resistance and was resulted found effective resistance. This line can be used MYMV donar. Conclusion of the studies are mungbean is highly compatible with other wild Vigna species. Donor development for different stress is possible in mungbean.
