为鉴定并筛选抗根肿病的油菜品种,2010年在云南省油菜根肿病的重发区保山市隆阳区板桥镇高海村,对9个主栽油菜品种和7个从国内各育种单位引进的品种进行根肿病抗性研究。结果表明:油菜苗期田间渍水,能明显加重根肿病危害,显著降低油菜最终收获产量;根肿病从苗期始危害油菜、薹期最重、成熟期危害发病率和病情指数均略有下降;供试16个品种对油菜根肿病的抗性可分为3类,其中A35、花油7号和云油双1号3个品种在全生育期均表现出较强的抗根肿病能力,可作为云南根肿病常发区主导品种和育种材料使用。
In order to identify and screen the rape varieties resistant to clubroot disease, in 2010, in Gahai Village, Banqiao Town, Longyang District, Baoshan City, Yunnan province, 9 main cultivars of rapeseed and 7 domestic cultivars Units introduced by the clubroot disease resistance study. The results showed that waterlogging in rapeseed field could significantly increase the risk of clubroot disease and significantly reduce the final yield of rapeseed. Root club disease harmed the rapeseed from the seedling stage, the boll stage was the heaviest, and the morbidity and disease index of mature stage were both slightly There were three types of tested rape clubroot disease resistance, of which, A35, Huayou 7 and Yunyou Shuang 1 were all resistant to root disease during the whole growth period Sickness can be used as a dominant species of clubroot disease in Yunnan and breeding materials used.
