Abstract
Evaluation of 26 F1 hybrids were involving two CMS lines and 13 restorers/testers in line × tester fashion, data recorded on ten agronomical characters. The four cross combinations viz., ICPA 2043 × Azad, ICPA 2043 × ICPR 4105, ICPA 2092 × ICPR 3760 and ICPA 2092 × MA 6, exhibited significantly high SCA effects for seed yield and the parents involved having high × high and low × low GCA effects. The four hybrids viz., ICPA 2043 × Asha, ICPA 2092 × Asha, ICPA 2043 × Azad and ICPA 2043 × ICPR 4105 showed good heterosis, MPH, BPH and EH, over commercial variety i.e. MAL 13 as well as inbreeding depression. Further, two hybrids (ICPA 2043 × Azad and ICPA 2043 × Asha) could manage to out yield the check, MAL 13, significantly with the margin of > 20 % and thus may be exploited for heterosis breeding in pigeonpea.
