摘要
本文通过对葡萄霜霉病抗病性鉴定方法进行优化,建立了一种更为快捷、方便、可靠的鉴定方法,并对32个葡萄品种对霜霉病抗病性进行了鉴定,为葡萄抗病品种的选育和应用提供依据。结果显示:以田间混合的霜霉病菌为接种体采用叶盘法鉴定葡萄品种的抗病性更加快捷、方便。供试的32个葡萄品种对葡萄霜霉病的抗性存在显著差异。其中免疫品种有‘康拜尔早生';高抗的有‘阳光玫瑰'、‘美乐'、‘Ms27-31'等5个品种;中抗的有‘贝达'、‘小芒森'、‘2E-16-2'等6个品种;低抗的有‘瑞都红玉'、‘早黑宝'、‘摩尔多瓦'等10个品种;感病的有‘里扎马特'、‘玫瑰香'、‘香妃'等10个品种。
This study aimed at establishing a more rapid,convenient and reliable method for identification of disease resistance to grapevine downy mildew via the optimization of resistance identification method.Resistance of 32 grape cultivars to downy mildew was identified.The results showed that using mixed strains and leaf disc method was more rapid and convenient for resistance identification.There were significant differences in the resistance to downy mildew among the 32 tested grape cultivars.‘Campbell early＇was the only immune cultivar.5 cultivars including‘Shine-Muscat＇,‘Merlot＇,‘Ms27-31＇etc.were highly resistant.6 cultivars including‘Beta＇,‘Petit Manseng＇,‘2 E-16-2＇etc.were moderately resistant.10 cultivars including‘Ruidu Hongyu＇,‘Zaoheibao＇,‘The Republic of Moldova＇etc.were weekly resistant,while 10 cultivars including‘Rizamat＇,‘Muscat＇,‘Xiangfei＇etc.were susceptible.
