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。
In order to help our wheat researchers fully understand the new races of Puccinia recondita-Ug99 and its potential threat to wheat production in China, we call for strengthening the monitoring of the spread and spread of Ug99 and its mutant races, and strengthening the innovation of disease-resistant germplasm and enduring resistance to disease Breeding new varieties, Ug99 in advance to prevent the harm. This paper summarized the current research situation of Ug99 in Ug99 on the races of Ug99, the distribution of pathogenicity, distribution and spread of disease-resistant genes in wheat and their relatives, the screening of linkage molecular markers and the strategy of resistance breeding. Ug99 is a new breed of Scutellaria pulcherrimus susceptible to races of small races, extremely virulent and rapidly expanding, most likely to have a global impact on world wheat production. The discovery and utilization of new disease-resistance genes in wheat and their relatives and the cultivation of new persistent disease-resistant varieties should be strengthened to control and prevent the harm of Ug99 and its mutant races.
