Plant genetic engineering offers dramatic potential in the improvement of kiwifruit quality. The efficient gene transformation systems have been established, and transgenic plants have been obtained, some transgenes are potential goal genes associated with fruit development, maturity, senescence and adversity resistant ability. This article discusses the advances of application of genetic engineering to the germplasm improvement of Kiwifruit, the isolation and cloning of aim genes, and the methods of gene transferring as well as the affecting factors. The prospects of its applications and several main problems are also discussed.
