Abstract
Seven varieties were studied by diallel analysis in 1972 and 1973. Additive genetic variances were significantly different from zero in both years and in both the F1 and F2 and additive effects of genes were more stable than dominance effects. The degree and direction of dominance varied with traits, generations and years, except for number of spikelets per node and number of spikelets per panicle which remained at partial dominance in both years and generations. Long panicle and large numbers of spikelets per node and spikelets per panicle were controlled by recessive genes, while large numbers of branches per node and branches per panicle were controlled by dominant genes. The dominant and recessive genes controlling panicle length and number of spikelets per panicle were in equal proportions in the parents, while an excess of dominant genes existed for number of branches per node and number of spikelets per ode. Number of spikelets per panicle had high heritability and appeared to be the most reliable selection criterion for yield improvement
