Abstract

Combining ability studies on some agronomic and grain yield and its components were done via Line x Tester analysis of 60 hybrids produced by crossing five basmati and one un-basmati CMS lines and ten basmati restorer lines including the un-basmati restorer variety Giza 178. The results indicated that plant height, panicle weight, filled grains panicle-1, spikelet fertility %, 1000-grain weight and grain yield (t/ha) were mainly controlled by additive gene action, while, days to maturity (earliness) and panicles plant-1 were mainly governed by dominance gene action (non-additive). Egyptian Pusa basmati 12A/B, 13A/B and 14A/B were general combiners among the female parents for most of the studied traits. The male parents Giza basmati 201, EPR30 and EPR25 were the best general combiners for most of the studied traits. Twenty seven out of the sixty hybrid rice combinations resulted from Basmati female and male parents exhibited significant desirable SCA effects for grain yield. The most desirable hybrids were IR58025A/EPR15, Pusa14A/EPR25, IR58025A/EPR16, Pusa13A/EPR1 and Pusa14A/EPR1.
