| Abstract |
Aiming at studying the breeding germplasm population of grain sorghum in Egypt, a sample of 30 lines was randomly selected to make 72 crosses according to line x tester scheme to form three sets. The lines and hybrids samples were referred to as lines and hybrids populations, respectively. The samples were evaluated in three separate experiments, simultaneously planted in two successive seasons.
The descriptive statistical parameters of plant height, days to 50% heading, 1000 kernel weight and grain yield were measured for both lines and hybrids populations. For 1000 kernel weight estimates of minimum value, lighter quartile, median, mean, heavier quartile and the maximum value were 22.00, 24.00, 25.55, 26.23, 27.70 and 35.90 g., respectively, for lines population and 17.00, 23.95, 26.7, 27.88, 31.10 and 42.60 g., respectively, for hybrids population. Results suggested the role of non-additive and effects in the inheritance of kernel weight. The minimum estimates of broad and narrow sense heritability for kernel weight were 92.80 and 58.52%, respectively.
The relationships between kernel weight and each of plant height, heading date and grain yield were studied using phenotypic and genotypic correlations as well as path coefficient analysis.
