| 摘 要： | 以东北农业大学大豆研究所选育的抗大豆胞囊线虫非小种特异性品种L-10为父本、黑农37为母本杂交所衍生的141个F2:8大豆重组自交系群体作为材料,采用塑料钵柱法在温室病圃对大豆重组自交系抗性进行鉴定,并对抗病性和主要农艺性状进行相关性分析.结果表明:大豆重组自交系寄生指数与株高、单株荚数、百粒重呈负相关;与花色存在相关,与种皮、种脐色存在显著相关.高抗品系呈现椭圆的粒形、黑色种皮、黑色脐、棕色茸毛为主,这些质量性状可为高抗大豆胞囊线虫品种的选育提供参考依据.

| Abstract: | The resistance of soybean cultivars to soybean cyst nematode(SCN) closely related with some agronomic traits.Therefore,studying the relationship between characters of SCN resistance and agronomic characters had great reference value for breeding practice.A recombinant inbred lines(RILs) population with 141 F2:8 individuals derived from the cross of L-10,a nonrace specific soybean line as male parent,and Heinong 37 as female parent,was taken as materials.Plastic bag method was introduced in greenhouse diseas... |
