摘要
以抗白粉病的日本小麦品种Fukuho-komugi和以色列小麦Oligoculm杂交F1的DH(doubled haploid)群体107个系为材料,利用313个SSR标记和37个RFLP标记,对Fukuho-komugi和Oligoculm的白粉病成株抗性进行QTL分析。试验材料于2003—2004年度种植在北京2、003—2004和2004—2005年度种植在安阳,调查白粉病发病情况。构建了由350个位点组成的遗传连锁图,覆盖小麦21个连锁群,全长3 101 cM。采用复合区间作图法进行白粉病成株抗性QTL分析,在1A、2B4、B和7D上发现4个抗白粉病QTL,分别解释13.6%、6.6%、8.9%和12.7%的表型变异。抗白粉病基因及其紧密连锁分子标记的发掘,将为小麦抗白粉病育种的分子标记辅助选择提供理论和技术支持。
