Abstract

Five parents of eggplant were crossed in a diallel cross system; i.e., SBI-1.1 (P1), SBI-3.3 (P2), SBI-10.13 (P3), SBI-11.14 (P4), and VS.1.13.19.1 Spain (P5), at El-Khattara Experimental Farm, Faculty of Agriculture, Zagazig University in 2005-2006 and evaluated in 2008 to study genetic components for some eggplant traits; i.e., plant height, branch number /plant, early fruit number, fruit weight / fruit in early yield, early yield / plant, total fruit number, fruit weight / fruit in total yield and total yield / plant. The results reflected insignificant t2 for all the studied traits, except early yield/plant which t2 was significant. By inspection, t2 was found insignificant after removing P4. For all the studied traits, the estimates of D, H 1 and H 2 were significant for all these traits. Asymmetrical gene distribution was observed, except total yield which had symmetrical gene distribution (0.25). For total yield, complete dominance was found to control this trait, and the dominance is isodirectional.
