油菜白锈病(Albugo candida(Pers)O.Kuntze)在西南、华东各省为害严重,其他各省也有分布,是油菜产区的重要病害之一。 1978—1984年对国内外甘蓝型油菜品种资源576份进行了抗源筛选鉴定,其中免疫者215份,占鉴定材料的37.33％;高抗者204份,占35.42％;中抗和低抗者116份,占20.14％;感病者41份,占7.12％。免疫和高抗材料是抗病育种的优良抗源。产量比较试验结果:齐菲(Zeph-yr)、东辐一号、小塔(Turret)和加拿大3号(Candian Rapeseed No.3)在夏播条件下抗病高产;东辐一号—03、花叶油菜和东辐一号在秋播条件下表现抗病高产。此外还有一些免疫、高抗品种在各地生产中表现经济性状良好,有直接利用价值。
Albugo candida (Pers) O.Kuntze is one of the most important diseases in the rapeseed production area. It is severely damaged in the southwestern and eastern China. From 1978 to 1984, 576 batches of domestic and overseaed rapeseed cultivars were screened for resistance to infection, of which 215 were immunized, accounting for 37.33% of the identified materials; 204 were highly resistant, accounting for 35.42% of the total; 116, accounting for 20.14%; 41 patients, accounting for 7.12%. Immune and highly resistant materials are good sources of resistance to disease breeding. Yield comparison test results: Zeph-yr, Dongfang 1, Turret and Canada 3 (Candian Rapeseed No.3) were resistant to disease under summer sowing conditions; Dongfang-1, Mosaic rape and Dongfang No.1 showed disease-resistant and high-yield under the conditions of autumn planting. In addition there are some immune, high resistance varieties in various parts of the production performance of good economic performance, direct use of value.
