| Abstract | ||
| Full diallel cross among five pure lines of sunflower (1) Eurflower, (2) Embrator, (3) Clab, (4) Elasol and (5) 6402, was used in this study. The parents F1's and reciprocal F1's were planted using randomized complete block design with three replications during autumn seasons of 2012. Data were recorded on characters plant height, leaf area, number of seeds per head, 500 seeds weight and seeds yield per plant, to estimate general and specific combining abilities and their effects, variance components and heterosis. The results showed highly significant differences among genotypes for most characters, and the mean square of general and specific combining abilities washighly significant for number of seeds per head and seeds yield per plant. The two parents (Embrator) and (Clab) significantly surpassed others in their general combining ability effects for most characters. The hybrids (EurflowerxEmbrator) and (Embratorx6402) characterized by significant desirable specificcombining ability for most characters, and the hybrids (Clab x Embrator) and (ElasolxEmbrator)significantly surpassed other reciprocal hybrids in the desirable direction for most studied characters. The hybrid (Elasol x Embrator)characterized by significant desirable heterosis of larger number of characters. Broad sense heritability ranged from high to moderate, while narrow senseheritability ranged between low and high. The average degree of dominance was higher than one for all characters indicating the presence of over dominance | ||
