为帮助我国小麦研究人员全面了解秆锈菌新小种-Ug99及其对我国小麦生产的潜在威胁，呼吁加强Ug99及其变异小种传播与扩散的监控，加强抗病种质创新和持久性耐病新品种选育，提前预防Ug99的危害。对Ug99小种变异、致病力、分布扩散以及小麦及其亲缘种属抗病基因发掘、连锁分子标记筛选，抗性育种策略与进展，中国Ug99研究现状进行了总结，由此不难看出，Ug99是容易发生小种变异、毒力极强、扩展速度较快的秆锈菌新小种，极有可能对世界小麦生产带来的全球性危害。应该加强小麦及其亲缘种属新抗病基因的发掘与利用和持久性耐病新品种的培育，控制和预防Ug99及其变异小种的危害。

This paper reviewed the research advances of Ug99 and its resistance breeding from the aspects of its discovery, race variation, pathogenicity, distribution, spread, exploration of relative resistant genes, linked molecular marker selection and resistance breeding strategies, to provide basis for comprehensive understanding of the new Puccinia graminis f. sp. tritici race Ug99 and its potential threat to wheat production. Ug99 is a new Puccinia grarninis f. sp. tritici race with high variability, strong pathogenicity and rapid spread speed, which is likely to cause global damages to world wheat production. We should strengthen the exploration and utilization of new resistance genes in wheat and relative species and breeding of new wheat varieties with durable resistance, to control and prevent damages caused by Ug99 and its variants.
