| 摘 要： | YAV-2/TEZ//A.SQ(895)是硬粒小麦与粗山羊草杂交获得的抗白粉病人工合成小麦。本研究利用人工合成小麦YAV-2/TEZ//A.SQ(895)与感白粉病的普通小麦品系品资50098杂交和自交获得的F2代群体及F3家系,在温室条件下鉴定群体的白粉病抗性。遗传分析结果表明,该抗白粉病基因为显性单基因遗传。利用647对小麦SSR引物进行了白粉病抗性基因的分子标记分析,结果表明该白粉病抗性基因与2A染色体的6个SSR标记连锁,与标记Xcfa2086的遗传距离最近,为11.8cM。

| Abstract: | YAV-2/TEZ//A.SQ(895)is a synthetic hexaploid wheat derived from a cross between T.durum Desf.and T.tauschii L.,which is immune to powdery mildew.Genetic analysis of resistance to powdery mildew in F2 population and the F3 families derived from a cross between YAV-2/TEZ//A.SQ(895)/3 and Pinzi 50098 indicated that a single dominant gene controlled the resistance.By bulk segregation analysis,microsatellite marker Xcfa2086 was identified to be closely linked to the resistance gene with the genetic distance of 1... |
