长期以来,在葡萄专家中存在着欧洲种葡萄品种不抗寒,不抗病,不抗虫的观点。根据不同地区品种圃内欧洲种葡萄基因资源的经济生物学性状的研究和对一些作为杂交原始材料的许多品种,以及后代的多年鉴定表明了欧洲种葡萄的许多品种不仅在产量、品质、成熟期上,而且在抗寒、抗旱以及抗病虫的遗传上都是杂合性的。为了客观地鉴定葡萄对根瘤蚜、霜霉病、灰腐
For a long time, there are grapes experts in European grape varieties are not cold, disease-resistant, non-insect-resistant point of view. Based on the economic and biological traits of European grape germplasm resources in different regions and many years of identification of many cultivars as hybrid origin materials and their offspring, many varieties of European grape varieties have not only been reported in terms of yield, quality, maturity , But also heterozygous in the cold, drought and genetic resistance to pest and disease. In order to objectively identify grapes on the phylloxera, downy mildew, gray rot
