Characterization of F1 hybrid grape produced from crossing between Alabbasi and Thompson seedless cultivars


This study was conducted at a private vineyard located in Abu-Ghraib/ Baghdad during 2003 and 2004 growing season to investigate the characterization of the F1 hybrid which produced by crossing between Alabbasi and Thompson seedless CV. and compared with the parents. The main results of the study can be summarized as follow: 1.The hybrid and its parents differ in their date of fruit maturity, the ripeness earlier than the parents and the differences was ranged from 5-15 days in the first season and 7-16 days in the second season.2.Alabbasi cv showed significant increased in yield quantity for both seasons except the F1/2 hybrid in the second season. Also Alabbasi cv resulted in a high significant increased with Thompson seedless and the hybrid for both seasons, while F1/1 hybrid gave lowest average weight of cluster for both seasons. Thompson seedless cv showed the highest average in number of cluster per vine for both seasons and significantly higher than F1/1 hybrid which resukted in a lower number of cluster/vine for both seasons.البحث مستل من أطروحة دكتوراه للباحث الأول3.There was a significant increase in average of berries size and weight of 100 berries and berries firmness in Alabbasi cv as compared with Thompson seedless and hybrid for both seasons.
