Genetic variability along with genetic advance of traits is essential for crop improvement.
Interspecific hybridization has great potential for the improvement of Vigna germplasm, as it creates genetic
variation and is a valuable tool for transferring genes controlling traits from one species to another. The main
objective of this research was to improve genetic variability and genetic background of Vigna germplasm
through interspecific hybridization. Four varieties of Vigna radiata with different characteristics were crossed
with two genotypes of Vigna umbellata and four genotypes of Vigna unguiculata were crossed with superior
variety of Vigna sesquipedalis. The hybrids were found to be viable and fertile. Genotypic coefficient of
variation and phenotypic coefficient of variation were different among cross combinations and among
quantitative traits. There were interspecific hybrids of V. unguiculata x V. sesquipedalis having good prospect
to be developed become hybrid vegetable bean containing high protein and anthocyanin. Through interspecific
hybridization and backcrossing of superior hybrids to their parents had improved genetic variability especially
number of pods per plant, pod length, plant height, pod texture, and nutrition content. The magnitude of
differences between phenotypic coefficient of variation and genotypic coefficient of variation were low for all
the observed characters. By crossing among vigna species, some superior characters can be obtained.
