A set of six cytoplasmic-genetic male sterile lines as female parents and thirteen diverse male parents used as testers and their respective hybrids generated in line x tester fashion were evaluated for their performance for eleven yield and its component characters. The highest superior performance for seed yield per hectare showed by the cross ICPA-2098 x Asha. The maximum number of pods per plant and seed yield per plant recorded by cross ICPA-2098 x M-3 (GRG-2009). The hybrids showed high performance for seed yield also recorded significant mean for other yield attributing characters also. Parents Asha, BSMR-736 and WRP-1 recorded superior performance seed yield per plant and the line GT-307A and tester BSMR-736 for seed yield per hectare. The high mean performance reflect their ability to produce heterotic hybrids, Hence, these superior parents could be used derive heterotic hybrids in pigeonpea.
