Abstract:
Snake bean is an important legume vegetable in Kerala but its production is affected by water stress. The present research was carried out to study the magnitude of heterosis for drought tolerant traits in snake bean, with the ultimate aim of selecting appropriate parents for hybridization in the development of drought tolerant varieties. The heterosis of twenty one hybrids produced by L x T mating of seven lines and three testers were estimated. The crosses L3 x T3 (Kattampally local x Vellayani Jyothika), L4 x T2 (Kulasekharapuram x Lola) and L6 x T2 (Nilamel local x Lola) were found to be superior for most of the traits studied. These crosses can be further utilized in hybridization programme to get desirable high yielding drought tolerant varieties.
