Interspecific hybrids involving four genotypes of mungbean (Vigna radiata L.) as female
and the three genotypes of urdbean (Vigna mungo L.) as male were studied. Genotypes
influenced crossability, germination, survival and fertility of Fts. The crossed seeds were
shrivelled and the Fts were partially fertile, late maturing and intermediate in morphology.
Purple colour of the stem was dominant overgreen colour. Only 2 out of 6 hybrids, namely,
BHUM 1 X Pant U 30 and T 44 X T 9 resulted in fertile Fts which reached maturity. Fertility
of the progenies improved from F2 to F4 generations. Desirable transgressive segregates
observed in the advanced generations open up new avenues for amelioration of these crops.
Keywords: Mungbean, urdbean, interspecific hybridization, transgressive segregation.
