| description | Traditional breeding methods produce high-yielding varieties with blast disease resistance. In this study, twenty-one F1s were evaluated for genotypic variation with seven parents; Analysis of variance showed statistically significant differences at the 0.05 level between all genotypes (crosses and parents). Blast and its constituent characters were also significantly affected by the mean squares of parents versus crosses. On the other hand, all of the F1 characters studied showed extremely high levels of variance in general combining ability (GCA) and specific combining ability (SCA). The best hybrid combinations for grain yield per plant were Sakha101 × Hassawi-1, Giza175 × Sakha103, and Gz9577 × Giza175. Regarding heritability estimates for all traits under consideration, the results revealed that heritability, in general, was high for all characters. Pearson's correlation found 15 correlation coefficients among the characters to be significant (p < 0.05). Flag leaf area, grain yield per plant, and milling percentage all had positive and highly significant correlations. |
