By using randomized complete block design (RCBD) in three replications. Six genetic types of eggplant used as parents (T1, T2, T3, T4, T5, T6). The objective was to determine the effect of heterosis in first filial generation F1 of some fruit quality parameters (Yield\/pl, total sugar%, soluble solids material%, acid percentage%, dry material%, and degree hardness kg\/cm2 of fruit). Hybridization was conducted by half-diallel crossing scheme to obtain (15) hybrids for all crosses. The results showed highly significant differences between the parental types for all the studied traits. The hybrid (T3\u00d7 T5) had the highest significant value of heterosis (24.998**) for yield\/pl. The fourth hybrid (T1\u00d7 T5) gave significantly the highest value of heterosis for total sugar percentage (%23.655**). The third hybrid (T1\u00d7 T4) showed the highest value for soluble solids material percentage (9.414**%), also the second hybrid (T1\u00d7 T3) for acid percentage (%- 9.942**). The hybrid (T3\u00d7 T5) for dry material (%15.237**), and hybrid (T5\u00d7 T6) showed the highest significant value of heterosis for degree hardness of fruit (22.258**) kg\/cm<sup>2<\/sup>.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\"><strong>Keywords:<\/strong> Eggplant, Half-diallel crosses, Heterosis, Protected cultivation.<\/span><\/p>\n<p><strong><span style=\"font-family: 'times new roman', times, serif;\">\u00a0Full paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v13n3p29.pdf\">PDF<\/a><\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hasan Asad1*, Hassan Khojah 2 and Ghaitha Hasan1 1 General Commission for Scientific Agricultural Research, Tartous Research Center, Syria 2.
