An investigation was carried out at Plant Breeding Farm, Department of Genetics and Plant Breeding, Faculty of Agriculture, Annamalai University to evaluate the parents (lines and testers) and their hybrids in blackgram for seed yield and its component traits with an objective of developing superior hybrids for recombination breeding and to understand the nature of gene action for ten productive traits. Line x Tester mating design was adapted using seven lines and three testers and twenty one hybrids. The ratio of GCA/SCA variance revealed the predominance of non-additive gene action for all the characters studied. The lines which recorded high seed yield per plant viz., L1 (2KU-53) and L4 (VBG 05-014) were good general combiners for many of the traits studied. The testers which showed high seed yield per plant viz., T3 (VBN-5) and T1 (T9) were good general combiners for many of the traits studied. Evaluation based on high per se performance, favourable gca effects and tester non significant sca effects of hybrids resulted in the identification of L1 x T3 (2KU-53 x VBN-5) and L6 x T3 (VBG-05-014 x VBN-5) for recombination breeding.
