| Abstract | ||||
| Present investigation was carried out during two summer seasons of 2018 and 2019 on a private farm in Gharbia Governoratethe with 15 genotypes including 5 lines and 10 F1’s of eggplant. The experiment was laid out in Randomized Block Design with four replications. The observations were recorded for 10 characters. The obtained results cleared that both GCA and SCA were highly significant in vegetative traits, earliness and fruit characteristics. The ratio between GCA / SCA were more than one in all studied traits under study. The estimates of General combining Ability effects (gca) indicated that parent 1 was best general combiner for fruit yield as number and weight of fruits, whereas the best specific crosses were cross 3 ×4 for number of fruits per plant and crosses 1 × 4 and 3 × 5 were best specific combiners for total fruit weight. Heritability estimates in broad sense were high for all studied traits, while heritability estimates in narrow sense were low for all studied traits except for chlorophyll content it was moderately high. | ||||
