通过不同方法对十字花科蔬菜根肿病耐病性进行研究。结果表明,温室根肿病菌接种,花油6号、花油8号均表现抗病(R),CR-千秋白菜表现高抗(HR),83-1白菜表现中抗(MR)。根肿病病田育苗移栽,星星在正反季均表现高抗(HR);83-1白菜正季表现抗病(R),反季表现感病(S)。根肿病病田直播,星星正季表现抗病(R),反季表现感病(S);83-1正季表现中抗(MR),反季表现高感(HS);不同品种根肿病病田直播,不同品种间对根肿病抗性差异明显,不同品种均表现反季发病比正季严重,病情指数高低顺序为83-1白菜>花椰菜>青菜>西兰花>苤蓝>中甘11。
The disease resistance of clubroot in cruciferous vegetables was studied by different methods. The results showed that the disease resistance (R) was inoculated in R. solani, P. oleifera 6 and Hua You 8, and high resistance (HR) to C. chinensis and 83-1 Chinese cabbage. Clubroot disease Seedling transplanting, stars in the positive and negative season showed high resistance (HR); 83-1 cabbage showed resistance in the season (R), off-season performance of the disease (S). The root swollen disease field direct seeding, stars in the season showed disease resistance (R), off-season performance of the disease (S); 83-1 positive season performance in the anti-MR, anti-seasonal high performance (HS) The results showed that there was significant difference in resistance to clubroot disease between different varieties. The incidence of off-season was significantly worse in different varieties than in the positive seasons. The order of disease index was 83-1 Chinese cabbage> Cauliflower> Broccoli> Broccoli> Zhong Gan 11.
