以部分黄瓜和甜瓜品种为试材,通过病害抗性组分分析法,对其霜霉病抗性进行了初步研究。结果表明:供试黄瓜、甜瓜品种均为感病品种;其中黄瓜品种“唐山秋瓜精品606”、“水果型101”(唐山秋瓜)、“及早挂满架”、“津研4号”、“绿宝2号”等,甜瓜品种“纯甜时代”、“高糖金玉”等感病较轻,表现为病斑相对较小,病斑数形成较少,病斑产孢囊量较少;黄瓜品种“吉杂4号”、“麻皮黄”等,甜瓜品种“如意”、“金甜佳美”等品种感病较重,表现为病斑相对较大,病斑数形成较多,病斑产孢囊量较多。
Taking cucumber and melon varieties as test materials, the resistance to downy mildew was studied through disease resistance component analysis. The results showed that the varieties of cucumber and melon were all susceptible cultivars. The varieties of cucumber, “Tangshan Qiuquanshengyu 606”, “Fruit 101” (Tangshan Qiucua), “ ”Jin Yan No. 4 “, ”Emerald No. 2“ and so on, melon varieties ”pure sweet age “, ”high sugar Jinyu “ and other susceptible mild, manifested as lesion is relatively small, The formation of lesion number is less, the lesion production of cysts less; cucumber varieties ”Jizhen No. 4 “, ”hemp yellow “, etc., melon varieties ”wishful“, ”golden sweet Caramel Other varieties of susceptible heavier, the performance of lesion is relatively large, the formation of more number of lesion, lesion cysts yield more.
