This study was carried out at the Experimental Farm, Faculty of Environmental Agricultural Sciences, Suez Canal University, El-Arish, during 2009 to 2010 seasons, to produce some new promising hybrids of eggplant, suitable to North Sinai region and similar area,and to determine some useful genetic parameters. Six cultivars of eggplant; viz., Spa-3, Spa-6, Black Beauty (B.B.), Ma-l, PIG-4 and Jor-3 were used as parental genetic materials. These cultivars were used to produce the all 15 possible hybrids among them in one way. The six parents, 15 F1 S and the (Classic) F1 (a check hybrid) were evaluated in winter seasons 2009/2010 under unheated plastic houses. The obtained results cleared that the over all F1 means surpassed those of parents and check hybrid in most studied characters. The highest total fruit yield was produced by the crosses Spa-6 x B.B, Spa-3 x Ma-l and PIG-4 x Jor-3. Heterosis over mid- parents were significant or highly significant, with positive values for most traits. Average heterosis over the better parent and check hybrid was insignificant for most traits. Correlations among the studied traits exhibited significant or highly significant positive or negative correlation values.
