条锈病流行对小麦生产造成巨大损失,选育和种植持久抗性品种是防治小麦条锈病最经济有效的策略.为达到多基因聚合培育持久抗病品种的目标,必须不断发掘抗病种质、解析其抗病遗传机制并开发分子标记.基于文献,对条锈病抗性基因发掘涉及的抗病性、分子标记、基因定位方法和定位进展及其在育种中的应用进行了综述,明确了小麦条锈病基因定位涉及技术的现状、局限性及优势,从而为后续的条锈病抗性基因发掘、多基因聚合和持久抗性小麦品种的选育与生产布局提供技术指导,以降低西北麦区和小麦主产区条锈病流行的频率,进一步促进国家粮食安全.
Research Progresses on Mapping of Wheat Stripe Rust Resistance Genesand Molecular Markers
The epidemics of stripe rust cause significant yield losses in wheat production.Breeding and cultivation of durably resistant varieties are the most cost-effective strategy for controlling wheat stripe rust.To achieve the goal of breeding durably resistant varieties through multi-gene pyramiding,it is necessary to continuously explore disease-resistant germplasms,decipher their resistant genetic mechanisms and develop molecular markers.This paper summarized the research progresses of stripe rust resistance,molecular markers,gene mapping methods,and their application in breeding related to the identification of stripe rust resistant genes to further clarify the status,limitations,and advantages of association mapping technologies for mapping of stripe rust resistance genes.This paper aims to provide technical guidance for the subsequent discovery of stripe rust resistance genes,multi-gene pyramiding,and the breeding and production arrangement of durably resistant wheat varieties to reduce the frequency of stripe rust epidemics in the northwestern wheat region and major wheat producing areas to further guarantee national food security.
