| Abstract | ||||
| In this investigation, six varieties of eggplant were set up in a factorial mating design (3 x 3) to obtain nine Fl hybrids. The resulted genetic material could help to obtain estimates for the different genetic parameters in addition to the estimation of heterosis. All genotypes were planted in two different locations (Mansoura and Sohag) to allocate the best genotype for each given location. The data showed variable results with respect to the performances of all genotypes. The best parent and the best Fl hybrid was not the same at both locations. The obtained values of heterosis from the mid-parents according to the combined data were 22.06, 29.15, 33.33, 13.59, 23.28, 15.46 and 72.10% for plant height (P.H.), number of branches per plant (No. B.lP.), number of leaves per plant (No. UP.), weight of fruit 0N.F.), fruit length (F.L.), fruit diameter (F.D.) and average yield per plant (AY.lP.), respectively. In the same time, the highest value of heterosis against the better parent was 26.92% for A.Y.lP. trait. The estimates of genetic variance components obtained from the factorial mating design showed the importance of additive (cr2A) and non-additive genetic variances including dominance (cr20) , although the magnitudes of (cr2o) were larger than their corresponding (cr2A). Concerning heritability values, the results indicated that the magnitudes of h2b% were larger than those of h2n% for all studied traits. These results illustrated the possibility of producing vigorous hybrids to increase the productivity of eggplant. | ||||
