| Abstract | ||
| The main goals of that recent study were estimating the nature of the characters inheritance for three common wheat crosses. Six-parameters model was followed to achieve mention objectives. The scaling test proved significant values for all studied characters, except for the number of spikes. plant -1. Additive and dominance effects controlled the number of spikes and grain yield. plant-1 in cross I, along with, 100-grain weight in crosses I and II. The magnitude of heterosis was significant (P ≥0.01) for all characters of the three crosses, except for the number of grains. spike-1 of cross I and III. Inbreeding had significantly affected 100-grain weight in any of the crosses and grain yield. plant -1 in cross II. Over dominance toward the higher parent (P ≥0.01) had recorded for all wheat characters, except for the number of spikes. plant -1 of cross II. Meanwhile, the values of over-dominance were towards the lower parent in the latter character. Heritability estimates ranged between 54.59% for (number of spikes. plant-1) and 85.77% for (100-grain weight) in cross I and II respectively. Expected genetic advance from selecting the upper 5% were recorded high for cross I and III. | ||
