与其它农作物生产一样,病害是危害葡萄生产的十分重要的因素。特别是在全世界广为栽培的欧亚种葡萄(Vitis vinifera)品种,虽然品质优良,但抗病性低,因此,化学防治在葡萄生产成本中,占有很大的比例。化学防治不仅增加生产成本,而且能造成环境污染和果实残毒。此外,化学防治也会使病原发生变异,产生新的抗药类型,使原来的农药失去效力。所以,如何将存在于葡萄属(Vitis)其它种中的抗病基因引入欧亚种中,以获得优质抗病新品种,一直是很多葡萄育种家努力的方向。
As with other crop production, disease is a very important factor that compromises grape production. Especially Vitis vinifera cultivars widely cultivated around the world, although their quality is good, but their disease resistance is low. Therefore, chemical control accounts for a large proportion of the cost of grape production. Chemical control not only increases production costs, but also causes environmental pollution and residues of fruits. In addition, chemical control will also cause pathogen mutation, resulting in new types of resistance, the original pesticide ineffective. Therefore, how to introduce resistance genes existing in other species of Vitis into Eurasian species to obtain new varieties with good disease resistance has always been a goal of many grape breeding efforts.
