Abstract

Thirteen parents involving nine lines and four testers of two sub species of the cultigen cowpea viz., unguiculata and sesquipedalis and their respective hybrids generated through L × T fashion were evaluated for their per se performance for 16 characters. The maximum seed yield and vegetable yield per plant was recorded by L4 × T2 (GP1024/Lola) and L9 × T4 (GP1231/VS 33), respectively. The crosses involving accessions GP 1238, 743 and 1126 with Lola, Vaijayanthi and VS 33 showed superior performance for single plant vegetable and seed yield, clusters per plant, earliness, pod length, crude fibre and crude protein content.
