A diallel analysis with six varieties of rice (Oryza sativa L.) revealed that both GCA and SCA variances were significant for panicle length, primary branches, spikelet number, 100-grain weight and grain yield. ‘CH. 4’, ‘Badshah Pasand’ and ‘Jilhore’ were good general combiners for grain yield. Five crosses, ‘Badshah Pasand’ with ‘CH. 4’, and ‘Jaya’, ‘Jamuna’ with ‘Jilhore’ and ‘NSJ. 200’ and ‘CH. 4’ with ‘NSJ. 200’ were superior for all the traits mentioned above. The first, a cross between high × high combiner, gave the highest SCA effect for grain yield. Reciprocal differences were not recorded in any case.
