SEX DETERMINATION OF KIWIFRUIT SEEDLINGS WITH MOLECULAR MARKERS
Turkey has very good conditions for growing most fruit crops economically. Kiwifruit was first introduced to Turkey in 1988 and has shown successful adaptation to the climate there, with the number of kiwifruit plants grown each year increasing exponentially. Nearly all orchards are of Actinidia deliciosa Hayward. In recent years, breeding efforts have been accelerated due to the increasing demand for new cultivars. However, the dioecious nature of Actinidia and the variation in ploidy level significantly influences the rate of success in breeding. Furthermore it is very important that the time for breeding is reduced. In this study, kiwifruit seedlings obtained from open pollination of several different cultivars were examined with different molecular markers for gender. In these different marker systems, specific bands for male and female individuals were investigated. Although several RAPD and SSR markers have been recommended by different researchers, separation of the seedlings according to gender could not be obtained. Polymorphic bands were obtained, however bands specific to male and female individuals were not identified, except for the case of one SCAR marker, Smy1. Elimination of male individuals is especially important in breeding, and our results show promise for further investigations.
