摘要

A field experiment was carried out with 56 F1 hybrids generated from line x tester design involving eight cytoplasmic male sterile and seven restorer lines in sunflower. Alongwith their combining ability, extent of standard heterosis were analyzed over the check KBSH-1 for five matric characters. Results indicated that the cross combination CMS M1A x RHA 23 showed highest heterosis for seed yield and oil yield followed by CMS 17A x RHA 23. The combinations of CMS 852A x RHA 278 and CMS 852A x RHA 378 were best maturing hybrids which showed highest negative heterosis for maturity over KBSH-1. The hybrid from the cross CMS 17A x RHA 378 manifested highest heterosis for test weight. CMS M1A x RHA 23 showed significant positive heterosis for head diameter. Among the 56 F1 hybrids studied, the cross combination of CMS 1A x RHA 23 and CMS 17A x RHA 23 exhibited positive heterosis for most of the characters with highest heterosis for seed and oil yield compared to check KBSH-1.
