A wheat stripe rust resistance gene was screened out from Aegilops tauschii which is relative genera of wheat species, broadening the genetic basis of the anti-disease character of wheat species. By hybridizing diversed Ae. Tauschii species, which is either resistant or susceptible to wheat stripe rust, a dominant wheat stripe rust resistance gene was detected from Ae. Tauschii (Coss.) Schmal Y206. The novel gene was temporarily designated as YrY206. By bulk segregation analysis, four microsatellite markers Wmc11a, Xgwm71c, Xgwm161 and Xgwm183 were found to be linked to YrY206 with genetic distances of 4.0, 3.3, 1.5 and 9.3 cM, respectively. According to the locations of the linked markers, the resistance gene was located on chromosome 3DS. Based on the chromosomal location and the resistance pattern of the gene, YrY206 should be a novel stripe rust resistance gene.
从小麦近缘属节节麦中筛选出一个小麦条锈病抗性基因，拓宽了小麦品种抗病性状的遗传基础。通过将对小麦条锈病具有抗性或易感性的不同节节麦物种进行杂交，从节节麦（Coss.）Schmal Y206中检测到一个显性小麦条锈病抗性基因。该新基因暂命名为YrY206。通过集群分离分析法，发现四个微卫星标记Wmc11a、Xgwm71c、Xgwm161和Xgwm183与YrY206连锁，遗传距离分别为4.0、3.3、1.5和9.3 cM。根据连锁标记的位置，该抗性基因位于3DS染色体上。基于该基因的染色体定位和抗性模式，YrY206应该是一个新的条锈病抗性基因。
