ABSTRACT

Genetic analysis comprising twelve diverse lines and four testers was undertaken in urdbean for six characters in F1 generation. Among lines, HPBU-124, HPBU-125, HPBU-130 and MX17 were good general combiners for most of the growth parameters. Tester PDU-1 revealed good general combiners for majority of the physiological traits including seed yield/plant. while Palampur-93 also performed good for leaf area/plant, leaf growth rate, net assimilation rate and crop growth rate. The study revealed that non-additive gene action was found to have a major role in the expression of all traits. The best specific cross-combination for seed yield was HPBU-125 x PDU-1, which involved both the parents with high gea effects. It was proposed that a breeding procedure which could make appropriate for the improvement of urdbean.
