Genetic variability was studied in pigeonpea breeding material comprising of five lines, three testers and their 15 crosses through line x tester mating design. Higher genetic variability was observed for primary and secondary branches per plant, pods per plant and seed yield per plant in crosses. In addition to these characters higher variability also observed for 100- seed weight, harvest index and phenol content in parents, indicating that greater variation in these characters offers greater scope to improve them through genetic manipulation. High heritability coupled with high genetic advance as per cent of mean was observed for secondary branches per plant, pods per plant, 100-seed weight, phenol content and seed yield per plant in crosses, while in addition to these characters, primary branches per plant, seeds per pod, pod length and harvest index in parents, indicating these characters are under the control of additive gene action. Hence, simple directional selection could be effective for improving these characters.
