针对我省油菜单产低,菌核病发病率一般在10～30％,严重的达50％以上的情况,江西省农科院植保所在1988年(收获年)对全省白菜型油菜品种资源进行了田间自然诱发抗性鉴定。鉴定材料115份,用稀水自作对照,选择历年菌核病发病严重的田块作自然诱发鉴定圃,地点省农科院旱作所农场。种子材料全由中国农科院油料所供给。按间比法排列,不设重复,每10个材料设1个或1个以上的对照。每份材料种植面积不少于检查所需30株(除去边行边株)。直播比当地同类油菜早10～30天,以诱发菌核病的发
For our province oilseed production is low, the incidence of sclerotinia is generally 10 to 30%, a serious case of more than 50% of the situation, Jiangxi Academy of Agricultural Sciences plant protection in 1988 (harvest year) of the province cabbage-type rape varieties resources The field naturally induced resistance identification. Identification of materials 115 copies, with dilute water as a control, select the incidence of sclerotiorum scab over the years for natural induced identification nursery, the Provincial Agricultural Institute of dry farming farms. Seed material by the Chinese Academy of Agricultural Sciences oil supply. Arrange according to the ratio method, no duplication, every 10 materials to set up one or more than one control. The area planted for each piece of material should not be less than 30 for the inspection (except for the sideline plants). Live rape earlier than the local rape 10 to 30 days to induce sclerotinia hair
