摘 要 :大豆胞囊线虫1号和4号生理小种是黄淮地区的优势小种,ZDD2315是我国特优抗源。本文旨在定位ZDD2315对1号和4号生理小种抗性的QTL。试验以Essex为母本,ZDD2315为父本和轮回亲本,创建了一个包含114个单株的BC1群体。采用250个SSR标记和1个形态标记通过MAPMAKER 3.0构建了包含25个连锁群的遗传图谱,覆盖大豆基因组2 963.5 cM
Abstract:Race 1 and Race 4 are predominant races of soybean cyst nematode (SCN) in Huang-Huai Valleys in China. The soybean land race, ZDD2315, was recognized as an elite resistance source for the races. The present study was aimed at mapping QTLs conferring resistance to Race 1 and 4 in ZDD2315. The mapping
