In view to invigorate hybrid rice breeding and exploration of heterosis in untapped, low productive genetic pool of non-basmati aromatic rice, altogether thirtyF1’s were generated in L x T design fashion with thirteen parents (3 testers and 10 lines), and were evaluated along with the parents to unravel the combining ability for 28 yield and yield contributing traits. The study revealed importance of both additive and non-additive gene effects in governing yield and yield components with preponderance of non-additive gene action for most of the yield components. The parental lines IET 21842 along with Tenduphool, Tulsimongra, Kumbhdev and Bhatamahsuri were found to be a good general combiner for most of the characters studied. Thirteen out of 30 hybrids evaluated were exhibited significant positive SCA effect (predominance of non-additive, inter-allelic interaction), indicated predominance of non-additive gene action. The crosses CRMS 31AxIET 21842, CRMS 32A x Tulsimongra and CRMS 31A x Chhinguchhi shown high sca effects for GY which found in high x high general combiner category (additive and/or additive x additive type gene effect, more fixable in nature). Therefore, there is high probability of obtaining good transgressive segregants in the progeny of these crosses for improvement of this trait.
