| Abstract | ||
| Complete diallel of seven durum wheat genotypes (Triticum durum Desf.) were used in Randomized Complete Block Design with three replications to study the architecture for traits number of days to 50% flowering, plant height, number of spikes/plant, spike length, number of grains/spike, biological yield/plant, grain yield/plant, harvest index, 1000-grain weight and protein percentage. Genetic variance components estimated by Jinks & Hayman procedure (1953). Linear graphic analysis was also done for the variance of parents (Vr) and covariance of parents with F1 rows (Wr). The results showed that Additive genetic variance was important in the inheritance of all characters except protein Percentage, where as dominant variance was important for the inheritance of all characters. The average degree of dominance was over-dominance for some loci. | ||
