The investigation was carried out with three male sterile lines and 10 restorers and their 30 hybrids along with the hybrid check, HRI-174. Maximum panicle exertion per cent was recorded for AMPS 18A (80.27%) and highest duration of floret opening was noticed for APMS 17A (153 min). APMS 15A was noticed to be a good combiner with high mean performance for un-filled grains per panicle, spikelet fertility per cent and 1000-grain weight, while, APMS 17A was to be a good combiner with high mean for grain density. In contrast, APMS 18A was noticed to be a good combiner with high mean performance for ear bearing tillers per plant. The results also revealed RTCNP 2 and RTCNP 38 to be good combiners for grain yield per plant, filled grains per panicle, spikelet fertility per cent and 1000-grain weight. A perusal of the results on mean performance, heterosis and specific combining ability revealed the superiority of APMS 15A x RTCNP 2, APMS 15A x RTCNP 150, APMS 17A x RTCNP 2 and APMS 17A x RTCNP 38 hybrids. These hybrids had recorded more than 30 per cent higher grain yield, compared to the check and were identified as promising rice hybrids in the study.
