摘要
通过2009—2010年在云南根肿病重发病区保山市隆阳区板桥镇进行油菜抗根肿病品种筛选试验研究,对云南省近年来主栽的9个油菜品种和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:人工模拟苗期渍害明显加重根肿病为害,显著降低油菜最终收获产量。根肿病从苗期始为害油菜、苔期最重、成熟期为害发病率和病情指数均略有下降。供试的16个品种抗根肿病能力大体可分为3个类群,A35、‘花油7号’和‘云油双1号’3个品种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。
The experiment focus on the research of resistance of rape variety to Plasmodiophora brassicae and screening with nine rape popular varieties in recent years in Yunnan Province and seven the introduced rape varieties from different breeding institutes in China from 2009 by 2010 in the high elevation Banqiao Town of Longyang, Baoshan of Yunnan Province, where has been the most severely Plasmodiophora brassicae region. Experimentation result indicated that water-logging obviously aggravate Plasmodiophora brassicae and reduce remarkably ultimate harvest yield of rape in manual simulation seedling stage. Plasmodiophora brassicae showed from rape seedling stage and aggravate during peduncle growth, the incidence and disease index of this disease modest declines in the maturity stage. 16 rape testing varieties basically can be divided into three groups by resistance to disease of Plasmodiophora brassicae, A35, ‘ Huayou 7＇ and ＇ Yunyou double 1 ＇ showed strong abilities on resistance to disease of Plasmodiophora brassicae in all of grow period, which served as predominant species and breeding materials in the Plasmodiophora brassicae regions of Yunnan Province.
