Abstract Inheritance of six oligogenic traits, namely, leaflet shape, twining nature, pod hairiness, growth habit, seed strophiole and seed colour, were studied in four intergeneric crosses involving two cultivars of C. cajan and three species of Atylosia. The genes responsible for leaflet shape, growth habit and seed colour showed incomplete dominance. For the remaining characters, dominant gene expression was recorded. The F, segregation revealed that lealet shape, pod hairiness and seed colour were governed by a single gene. The twining nature, seed strophiole, and growth habit were governed by two genes.
