Interspecific hybridization in Luffa was done to obtain a cultivar with a combination of traits from L. cyllindrica such as good yielding ability, tolerance to pests and environmental stresses as well as ease of processing and traits from L. acutangula such as sponge fiber compactness, fineness, and thickness. Two trials were conducted involving five hybrids of Luffa in 1991 and eight hybrids in 1992, together with their respective parental lines and Talisay (OP) as check variety. The interspecific hybrids excelled in terms of yield which was largely attributed to heterosis. Furthermore, the hybrids showed field resistance to melon fly (Dacus cucurbitae) and improved sponge thickness and fiber compactness. Hybrid SmP-1 x RdP-1 (or LIH-9101) showed consistent performance with yield advantage ranging from 240 percent to 279 percent over the check 'Talisay'. Initial results of on-farm trials showed farmers' preference for the interspecific hybrid LIH-9101 over the farmers' variety.
