Abstract:
Heterosis for grain yield, rancidity and associated characters was studied in pearl millet in line × tester design. Thirty twocrosses were generated using eight CMS lines and four testers and evaluated along with parental lines and two checks to estimateheterosis for ten characters in pearl millet. Non-additive gene action was predominant for all the characters under study excepteffective tillers per plant. None of the hybrids showed significant heterosis over the check 86 M 86 for grain yield, while hybrids92777A × R22, 97111A × R39 and 04999A × 08222R showed significantly positive heterosis of 254.81, 230.28 and 214.98respectively over the check HHB 67. The hybrids 03666A × 08222R, 05444A × 08222R and 98222A × 08222R exhibitedsignificantly lower negative standard heterosis over the check 86 M 86 for alcoholic acididty at 5th day of storage indicating higherlongevity in these lines.
