A combined process of chemical control of clubroot in Chinese cabbage at different growth stages was carried out. The test results showed that fluazinam and cyazofamid were effective pesticides for control of clubroot.

在大白菜的不同生育期，采用多种杀菌剂和不同的防治方法防治大白菜根肿病，试验结果表明： 50%氟啶胺和10%氰霜唑能有效防治大白菜根肿病，其防治效果优于其他化学药剂。

Plasmodiophora brassicae causes clubroot of cabbage and related brassicas .

如芸苔根肿菌引起的甘蓝和芸苔根肿病。

Clubroot A serious disease of the cabbage family caused by Plasmodiophora brassicae, in which the roots become swollen and misshapen, with characteristic gall-like swellings.

根肿病：由芸苔根肿菌 Plasmodiophora brassicae所引起的甘蓝类植物的一种疾病。植物患病后，根往往变得肿胀畸形。

In this study the clubroot resistant CR DH line, susceptible inbred line 94SK of Chinese cabbage, the resistant and susceptible DNA bulks constructed from F2 individuals of CR DH line and 94SK were used to select the adaptive AFLP primer combination. AFLP analysis was performed with 256 Pst Ⅰ/Mse Ⅰ primer combinations.

为了筛选出大白菜适宜的AFLP引物组合，研究以抗根肿病大白菜双单倍体CR Shinki、感病自交系94SK及其后代F2构成的纯合抗病和纯合感病DNA混合池为材料，利用256对Pst Ⅰ/Mse Ⅰ引物组合进行了AFLP分析。

The result shown that potassium permanganate , calcareousness lime and compost were plant protect material for control Plasmodiophora brassica,The result were affected by different applying period and applying method .

实验结果表明，有机肥、石灰、石灰水、高锰酸钾可以作为控制根肿病防治的物质，随着使用时间和使用方式的不同，对根肿病和蔬菜的产量的影响不同。

Calcareousness lime and plant ash could control this disease applied only, the optimum applying method is mix potassium permanganate with calcareousness lime base on compost in different plant period in growing season..

石灰或草木灰塘施或对水浇施，腐熟农家肥和石灰或高锰酸钾配合使用对根肿病的发生均有较好的抑制作用；单施农家肥和高锰酸钾对根肿病控制效果不理想，用腐熟农家肥作底肥＋1%石灰水播种后浇塘＋1%石灰水三叶期浇根＋1%石灰水六叶期再浇根的组合模式可以有效地控制对根肿病的发生与危害。

And then, Plasmodiophora brassicae were inoculated on transformed roots and transformed plants respectively for identification and screening of club root disease-resistant transformants.

根据转化体上根肿病的发病程度，评价不同转化系对根肿病的抗病性表现以及抗病转化系的抗病机理。

Transformed roots were inocuiated with resting spores of Plasmodiophora brassicae. On solid MS medium, the resting spores infected root haires but not root cortical tissues, and therefore no syndrome of club robt disease was found.

用根肿菌休眠孢子接种离体培养的转化根，结果发现，在固体培养基上，根肿菌只侵入根毛内，不侵入根皮层组织，因而不表现根肿病的任何症状。

Among transformed plants of cabbage and cauliflower, there were several transgenic lines having club root disease resistance.

在甘蓝和花椰菜的转化群体中，出现了抗根肿病的转化系，它们在温室和培养室内对根肿病的抗病性是相对稳定的。
