摘要
对引自原苏联的簇毛麦(HaynaldiavilosaL.Schur2n=14VV)及其与硬粒小麦杂交育成的双二倍体TH1TH1WTH2WTH3TH3W,普通小麦-簇毛麦6D/6V异代换系及普通小麦亲本和已知抗白粉病基因的18个小麦品种为供试材料,用84个来自美国、德国、中国的小麦白粉病菌菌系进行苗期接种鉴定。发现簇毛麦及其衍生系对所有参试的白粉病菌系表现免疫和抗,比供试的已知抗性基因的18个小麦品种抗性强,抗谱广。其抗性基因在81086A、D311、墨75、陕7859、宛7107、冀麦30等小麦遗传背景下均能很好表达。
Resistance to eighty four isolates of Blumeria graminis f. sp. tritici was identified in Haynaldia villosa (2n=14, VV), five amphiploids (2n=42, AABBVV), TH1, TH1W, TH2W, TH3, and TH3W, derived from crossing Triticum durum (2n=28,AABB) with H.villosa , and hexaploid substitute wheat lines 6D/6V, pm93064 (DH 2), derived from H. villoas . The results showed that the H. villosa and its derived wheat lines were immune or high resistant to all tested isolates from America, Germany and China. The resistance was more effective than any other resistance gene lines from pm1 to pm20, and the resistance gene has been transfered effectively to tetraploid and hexaploid wheat from H. villosa , and also was inherited to the progenies.
