葡萄营养丰富,用途广,结果早,适应性强,是酿酒上品。在全世界栽培面积和产量均超过了柑桔、香蕉和萍果,居于首位。我国广大地区是适宜发展葡萄的,唯现有品种多存在病害严重,不抗寒,不抗湿和果实糖分低的问题。解决这些问题的根本途径是选育高糖、优质、抗逆性强的综合新品种。但由于果树育种长期以来仅用少数栽培品种杂交,使杂交后代的基因贫化,种间杂交不易取得突破性成果。为了扩大育种基因,用 Grapes nutritious, versatile, early results, adaptability, is the wine quality. Cultivated area and output all over the world are more than citrus, banana and apple, in the first place. The vast majority of our country is suitable for the development of grapes, but the existence of many existing varieties of serious disease, no cold, no moisture and fruit low sugar problems. The fundamental way to solve these problems is to breed high-sugar, high-quality, strong comprehensive resistance new varieties. However, since fruit tree breeding has long been crossed with only a few cultivars, the genes of hybrids will be depleted and interspecific hybridization is not easy to achieve breakthrough results. In order to expand breeding genes, use
