在我国的中北部地区种植葡萄,每年冬季要复盖防寒,不但耗费很多劳力,和用于复盖材料的资金,而且在上架下架时,容易发生机械伤害,造成产量上的损失,这就在一定程度上限制了葡萄事业的发展。因之培育出各季不需要防塞的葡萄品种,在葡萄生产上具有重大的意义。我们从1951年开始就在兴城进行了这项工作,现在把初步的结果介绍在下面。一、试验材料和方法在抗寒育种中,我们利用山葡萄(vjtis amureus-is)作为父本,山葡萄广泛分布在东北地区,以小兴安岭和长白山最多,它的抗寒力极强,可抗-40℃以下的低温,它是东北中北部地区酿造葡萄酒的主要原料。山葡萄的缺点是含糖量低,含酸量高,出汁率
Planting grapes in the central and northern regions of our country will cover the cold every winter, not only consuming a lot of labor and funds for covering materials, but also causing mechanical damage and causing losses in production when shelving shelves To a certain extent, limited the development of grape business. It is of great significance in the grape production to cultivate the grape varieties that do not need to be stuffed in the seasons. We have done this work in Xingcheng since 1951, and we present the preliminary results below. First, the experimental materials and methods In the cold breeding, we use the grapevine (vjtis amureus-is) as a male parent, grapevine widely distributed in the northeast region, the largest of Xiaoxing’anling and Changbai Mountain, it is extremely cold-resistant, resistant to -40 ℃ below the low temperature, it is northeast northeast brewing wine main raw material. The disadvantage of mountain grapes is low sugar content, high acid content, juice yield
