Fifty two hybrids were generated from crossing four CMS lines and thirteen restorer lines in line x tester design. Crosses along with parents were evaluated for yield and yield component traits during rabi, 2011 at RARS, Jagtial, Andhra Pradesh. Predominance of non additive gene action was recorded for all the characters. Among CMS lines APMS 9A andAPMS 10A and in testers viz., MTU II-110-9-1-1-1-1, MTU II -187-6-1-1, MTU II-143-26-2, MTU II-290-42-1 and MTU II-283-7-1-1 were found to be good general combiners for grain yield and yield component traits. The crosses APMS 10A x MTU II-290-42-1, APMS 6A x MTU II -187-6-1-1 and PMS 6A x MTU II-110-9-1-1-1-1 were identified as most promising hybrids for grain yield plant-1. These hybrids can be tested over locations before their commercial cultivation. |
