Eight parents of aromatic rice were crossed in half diallel mating design without reciprocal including parents. The parents were evaluated for eleven different characters. Genetic analysis was done through Griffing’s Method II Model I. Analysis of variance revealed highly significant differences among parents and their crosses for all the characters. Combining ability analysis revealed that gca and sca variance were highly significant for most of the characters studied in F1 generation. Amongst the parental lines, Basmati Kasturi was a good general combiner for plant height at maturity, total number of spikelets per panicle, total number of filled grains per panicle and grain yield per plant in F1 generation while the most promising specific combiners for grain yield per plant were Basmati x Chakhao Angangba and Basmati Kasturi x Basmati 370.
