Interspecific hybridization in between L. operculata and L. acutangula brings out certain features of great relevance for tracing inter-relationship between these species. The F1 plants of L. acutangula×L. operculata and their reciprocal are fertile. All hybrids possessed the monoecious sex-form. A detailed cytological investigation in the F1 hybrid between L. acutangula×L. operculata and their reciprocal has been done. The inheritance studies of certain economically important characters like fruits in the hybrid have been made.
