不同葡萄品种对霜霉病的田间苗期抗性评价

摘要

对36个葡萄品种（品系）苗期对霜霉病的田间抗病性进行了评价，结果表明，不同葡萄品种（品系）对葡萄霜霉病的抗性存在明显差异，绝大多数欧美杂交种的抗性要强于欧亚种葡萄，供试的10个欧美杂种中，‘瑞峰无核’对葡萄霜霉病表现为高抗；‘DEMIR’、‘龙宝’、‘红富士’、‘黑奥林’、‘峰后’5个品种表现为中抗。%Germplasm resources of 36 cultivar grape varieties were analyzed to evaluate the resistance to Plasmo-para viticola .The results showed that there were significant differences in the resistance of the seedlings of differ-ent grape varieties towards grapevine downy mildew.The interspecific hybrids of Vitis vinifera and V .labrusca were highly resistant than all other varieties.Comprehensive resistance evaluation indicated that ‘Ruifeng seed-less’showed high resistance,and ‘DEMIR’,‘Longbao’,‘Hongfushi’,‘Black Olympia’and ‘Fenghou’,showed moderate level resistance.
