对国内外８８２份油菜种质资源进行抗（耐）菌核病的鉴定结果，未发现对菌核病免疫的种质，但获得高抗（耐）种质３７份，中抗（耐）种质６１份。在芸薹属６个栽培种中，复合种抗性强于基本种，其中以埃塞俄比亚芥最强，白菜型油菜最弱。新疆野生油菜抗性也较强。不同种质的生育期与抗（耐）病性密切相关，开花期迟的晚熟种质一般抗（耐）病性较强。在同一熟期的种质中，无花瓣油菜的菌核病发病率和病情指数分别下降３０．２％和３８．８％．来自德国及我国长江下游的中晚熟种质表现有较强的抗（耐）病性。
The identification of resistance to sclerotinia in 882 rapeseed germplasm resources at home and abroad showed no germplasm immunized against sclerotinia, but 37 accessions of high resistance (resistant) germplasm, Quality 61 copies. In Brassica 6 cultivars, the composite species is stronger than the basic species, of which Ethiopian mustard strongest, weakest Brassica campestris. Xinjiang wild rape resistance is also stronger. The growth period of different germplasms is closely related to the resistance to (disease) resistance, late maturing flowering late general germplasm (resistance) is more resistant. In the same maturity germplasm, the incidence and severity of sclerotinia in the petal rape decreased by 30.2% and 38.8%, respectively. Medium and late-maturing germplasms from Germany and China’s lower reaches of the Yangtze River show strong resistance to disease.
