Abstract
A study involving three genetic male sterile lines and nine diverse testers of early duration pigeonpea revealed that non-additive genetic variance chiefly controlled the expression of yield/plant and attributes such as primary branches/plant, pods/plant, seed/pod, 100-seed weight whereas additive genetic variance predominantly governed the expression of days to 50% flowering and plant height. Among male sterile lines ms Prabhat DT and ms Prabhat NOT were good general combiners and among testers ICPL 88001 was found to be the best general combiner, for yield/plant. Eight hybrids showed significant sca effect for yield/plant, and atleast one good combiner was involved in the six hybrids viz., ms Prabhat NOT x ICPL 85010, ms Prabhat NOT x P 610, ms Prabhat DT x UPAS 120, ms Prabhat DT x AF 98, ms Prabhat DT x ICPL 88001 and ms Prabhat DT x H 87–24.
