Abstract: The present investigation was carried out at the Experimental farm of Regional Agriculture Research Station, Karjat (Raigad). Studied the performance of F1s along with their parents and three standard checks was done during kharif 2016. The higher mean of hybrids for total number of spikelets panicle^-1 (253.59) was recorded over testers, lines and standard checks 235.19, 244.67, 223.86 respectively. The higher mean of hybrids for number of filled spikelets panicle^-1 233.70 over testers (200.77), lines 216.71 and standard checks 192.49 was recorded. The higher mean of hybrids for spikelet fertility 92.16% was recorded over testers, lines and standard checks 85.52%, 88.85% and 85.51, respectively. The higher mean of hybrids for grain yield plant^-1 31.92 gram was recorded over testers, lines and standard checks 23.80 gram, 24.20 gram and 30.47 gram. Among the male parents, NPQ-49 recorded higher mean performance for most of the characters and identified as good combiner for some of traits while as among the females, line IR58025B recorded higher mean performance and identified as good combiner for most of the character, could be utilized for further hybridization programme. On the basis of per se performance, the hybrids viz., IR58025A x NPQ-49 and RTN12A x NPQ-49 was found to be the most promising and may be evaluated critically to judge its superiority in performance and seed production technique for its utility on commercial scale.
