油菜品种对油菜菌核病的田间抗性评价

目的]筛选生产上可用的油菜菌核病抗性品种。方法]采用自然接种法对30个安徽主栽油菜品种进行抗菌核病鉴定和利用评价。结果]在鉴定的30个品种中，抗病、中感、感病和高感4个抗感类群分别占品种数的10.0%、76.7%、10.0%和3.3%，中感以上品种占80.0％，没有高抗类型。最感病品种为秦优10号，最抗病品种为沣油792F1。结论]为合理利用抗病品种防治油菜菌核病提供了理论依据。

Field Resistance Evalua-tion of Rapeseed Varieties against Sclerotinia scle-rotiorum

Objective] In order to screen rapeseed varieties which were re-sistant to Sclerotinia sclerotiorum. Method] 30 rapeseed varieties were identified and evaluated for resistance to Sclerotinia sclerotiorum by the method of nature inoculation under field conditions. Result] The results showed that resis-tant, medium susceptible,susceptible and high sensitive varieties accounted for 10.0%,76.7%,10.0% and 3.3% among the 30 varieties, respectively.Resistant and medium susceptible varieties ac-counted for more than 80.0%, and there was no highly resistant variety. The most susceptible variety to Sclerotinia sclero-tiorum was Qinyou 10,and the most re-sistant variety was Fengyou 792F1. Con-clusion] The paper provides a basis for rational use of resistant varieties to con-trol Sclerotinia sclerotiorum.
