【摘要】 从山东省农业科学院作物所提供入库的70 份大豆种质资源中获得5 份(3 份高抗和2 份中抗)对大豆胞囊线虫1 号生理小种表现抗性的种质。11 份对1 号生理小种表现免疫或高抗的种质9 年间表现稳定。对1 号小种表现高抗的种质资源RN-9 在熟期等重要农艺性状、对田间胞囊量消长的影响和对病原侵染力的选择作用等方面明显优于国内外广泛应用于育种计划的Peking、哈尔滨小黑豆等其他抗源。更多还原

【Abstract】 Five (3 high resistance and 2 moderate resistance) germplasms with resistance to race 1 of soybean cyst nematode(SCN) were screened out from 70 local germplasms of Shandong. The results showed that expressions of 11 resistant resources to race 1 of SCN were consistent in 9 years. RN 9, with superior agronomic characters to Peking, Harbinxiaoheidou and other resistant germplasms in maturity, antilodge, etc., was a good parent of breeding programs for soybeans with resistance to race 1 of SCN.更多还原
