我国小麦条锈菌生理小种毒性基因及致病性特点分析

 本文首次研究了我国小麦条锈菌生理小种的毒性基因型,探讨了我国小种与国际命名小种的关系,证实了我国条锈菌系具有与世界其它地区菌系所不同的独特致病毒谱,指出条锈菌在中国的流行是一个相对独立的区系。讨论了我国现有小种致病性及毒性基因进化关系。

ANALYSIS OF PATHOGENICITY AND VIRULEMCE FACTORS OF CHINESE RACES OF PUCCINIA STRⅡFORMIS TRITICI

More than 40 races from both inside and outside of China were tested by known Yr-sene cultivars, Chinese differentials, world and European differentials respectively.It was suggested that the CYR (Chinese Yellow Rust) -races possessd significantly different pathogenic spectrum from the races in the other parts of the world, which indicated that China was a relatively independent epidemic region for the disease.The comparison on discriminating ability of the differential sets and the possible evolution routes of the present CYR=races were discussed.
