Abstract
Forty-five crosses from a 10 X 10 diallel, combining geographically diverse varieties, were studied in the F1, F2 and F3 generations. Grain yield, days to flowering, plant height, lengths of panicle and primary branch, grain size and 100-grain weight were found to be highly heritable. Additive genetic variance decreased in successive generations, though considerably less than nonadditive variance. General combining ability tended to decrease in successive generations, though little change occurred in genotype rankings. No clear trend was observed for specific combining ability. The best crosses tended to be between parents of divergent general combining abilities
