In agricultural crops, interspecific hybridization is a useful tool to introduce novel variations for desirable traits across species and to ultimately widen the available genetic variation. Mungbean yellow mosaic virus disease (MYMV) is a major devastating disease in mungbean crop. Non availability of resistant source in cultivated mung bean, the closely related semi-domesticated species viz., Vigna stipulacea with MYMV resistant genes could be introgressed in cultivated mungbean (Vigna radiata). In this study, wide hybridization was attempted between Vigna stipulacea and Vigna radiata to fill the gap in knowledge in terms of crossability and barriers if any between these two species. Successful hybrids were obtained by crossing between mungbean as female parent and Vigna stipulacea as male parent. Whereas, the reciprocal crosses failed to set hybrid seeds, indicating the presence of pre-fertilization barrier in those crosses. Further, evaluation of hybrids and segregating generation revealed reduced fertility, which suggests backcross as an ideal alternate option to introgress desirable alleles from Vigna stipulacea into mungbean.
