| Abstract | ||
| The study included F2 hybrids resulted from the selfing of F1’s from half diallel wheat crosses among five parents (Intesar, Rabbea, Abu-Greeb-3, Adnanyia and Al-Eaz) to estimate gene action through variance components, Average degree of dominance, broad sense and narrow sense heritability for biological yield, plant height, number of spikes, spike weight, number of grains per spike and grain yield. Seeds of parental varieties and their F2 generations for diallel crosses were grown at the plant experimental station, during the growing season (2002-2003) according to the randomized complete block design with four replications, under rainfall conditions. The results showed over dominance for the most studied traits with high values for broad and narrow sense heritability. | ||
