中文摘要:

条纹锈,由 Puccinia striiformis f 引起了。sp。tritici,是在中国的小麦的主要疾病之一。以便抵抗铺平的驴和在从美国的和平的西北( PNW )的 59 小麦栽培变种(线)之中的存在的年基因,在中国为小麦条纹锈抵抗的基因改进提供抵抗资源,从美国的 PNW 的 59 小麦栽培变种(线)被在幼苗和成年植物阶段评估他们的抵抗的占优势的中国条纹锈赛跑 CRY31 , CRY32 ,和 CRY33 的 3 混合赛跑感染,并且紧与分子的标记屏蔽了59 美国栽培变种(线) ,五栽培变种(线) , Expresso, 02W50076, ACS52610, WA008012,和 WA00801833,有的所有阶段抵抗,到 CRY31 的混合赛跑的出现抵抗, CRY32,和在幼苗和成年人的 CRY33 种阶段。33 栽培变种(线) 有成年植物抵抗,仅仅出现的抵抗到在成年舞台的条纹锈。基于分子的屏蔽,任何一个都没 59 PNW 栽培变种(线) 有连接标记的多态的乐队到 Yr10。有 12, 33 和 29 栽培变种(线) ,有连接标记的多态的乐队到 Yr15, Yr18 和 Yr39,为 59 PNW 栽培变种(线) 中的 20 个, 55 和 49% 的财务分别地。所有这些结果建议 Yr15, Yr18 和 Yr39 在 PNW 栽培变种(栽培变种) 之中是普遍的并且能在中国小麦条纹锈抵抗繁殖被利用。

英文摘要:

Stripe rust, caused by Puccinia striiformis f. sp. tritici, is one of the major diseases of wheat in China. In order to asses the resistance levels and existing Yr genes among 59 wheat cultivars (lines) from the Pacific Northwest (PNW) of the United States, to provide resistance resources for genetic improvement of wheat stripe rust resistance in China, 59 wheat cultivars (lines) from PNW of the United States were infected by 3 mixed races of predominant Chinese stripe rust races CRY31, CRY32, and CRY33 to evaluate their resistance at seedling and adult plant stages, and screened with molecular markers tightly linked to currently effective all-stage resistance genes YrlO, Yrl5 and adult plant resistance genes Yrl8, Yr39. Of 59 American cultivars (lines), five cultivars (lines), Expresso, 02W50076, ACS52610, WA008012, and WA00801833, had all-stage resistance, showing resistance to mixed races of CRY31, CRY32, and CRY33 at both seedling and adult plant stages. 33 cultivars (lines) had adult plant resistance, only showing resistance to stripe rust at adult stage. Based on the molecular screening, none of the 59 PNW cultivars (lines) had the polymorphic bands of linked markers to YrlO. There were 12, 33 and 29 cultivars (lines) which bad polymorphic bands of linked markers to Yr15, Yr18 and Yr39, accounting for 20, 55 and 49% of the 59 PNW cultivars (lines), respectively. All these results suggested that Yr15, Yr18 and Yr39 were widespread among PNW cultivars (cultivars) and could be utilized in Chinese wheat stripe rust resistance breeding.
