Abstract

Five male sterile lines of pearl millet were crossed with ten restorer lines. The resultant 50 hybrids were evaluated for different productivity traits such as plant height, days to 50% flowering, productive tillers plant −1, panicle length and grain yield. From these observations, combining ability and heterosis were calculated to select the best performing parents as well as hybrids. Male sterile lines ICMA-95555:: and ICMA-95444 were noticed to be the best general combiner for grain yield and panicle length. The restorer RIB-212S-99 and RIB-1915-99 were identified as good general combiners. Among the crosses, ICMA-95555 x RIB-264S-99, ICMA-95555 x RlB-191S-99, ICMA-95444 x RIB-209S-99, RMS-6A x R1B-204S~99, ICMA-95444 x R1B-208-99 and ICMA-95555 x RlB-212S-99 were recommended for higher grain yield through heterosis breeding. The hybrids produced by different male sterile lines, ICMA-95444 and ICMA-95555 showed also higher heterosis for grain yield which is in tune with the results for general combining ability.
