一、初期工作近百年来,选育葡萄抗霜霉病的各种发展趋势是容易看出的。由美洲种(V.labrusca)直接产生了第一批杂种(H.P.D.)。此后,用美洲种之间杂交,或再用欧洲葡萄与美洲种之间杂交,《例如“OthelIe”品种为V.labrusca×v.riparia×V.vinifera》。单用欧洲葡萄品种间杂交,所获得的品种,在品质和产量上,均有很大的提高。在葡萄根瘤蚜危害后,由于H.P.D.杂种 First, the initial work Nearly a century, breeding grape downy mildew resistance trends are easy to see. The first hybrids (H.P.D.) were produced directly by V. labrusca. Thereafter, crosses between the American species or between the European grape and the American species are repeated, “for example.” “OthelIe” is a V. labrusca × v.riparia × V.vinifera. Single European grape hybrids, the varieties obtained, in terms of quality and yield, have greatly improved. After the grape phylloxera damage, due to H.P.D. hybrids
