| Abstract | ||||
| Nine parents of rice were crossed to obtain 36 F1 hybrids, through half diallel cross. These parents included one exotic variety, four commercial varieties and four promising lines. Hayman's 1954 method was employed for this purpose. The nine parents and their F1s were grown in randomized complete block design with three replications at the Rice Research and Training Center Farm, Sakha, Kafr El-Sheikh, Egypt. Results revealed highly significant mean squares for all characters, suggesting the presence of genetic differences among genotypes for all studied traits. Significant or highly significant and positive of additive component (D) for all characters except for panicle weight and number of panicles plant-1 were found. The dominance components H1 and H2 were highly significant for all characters studied. The environmental component (E) was insignificant for all characters except spikelet fertility% and grain yield plant-1. Heritability estimates in broad sense were high for all studied characters. The nine parents were distinctly classified into five clusters (below 25 Euclidean distance) according to the similarity. | ||||
