中文摘要：

对来自全国7个省市一定地域、不同年份、不同批次的15个落叶松-杨栅锈菌菌系进行了鉴别寄主反应型测定以及潜育期、产孢量观察,进一步明确了落叶松-杨栅锈菌在我国的生理小种分化。结果表明,15个菌系中的13个分别属于4个生理小种,Th053、Sb和Cj052归1号生理小种CMLP1,Ts06、Gl051、Hb05-1和Sb052归2号生理小种CMLP2,Qh063、Gl052、Hdao和Sb051归3号生理小种CMLP3,Bq和Qh061归5号生理小种CMLP5,By05-3和Zs暂单独划为1个致病类型。

英文摘要：

Fifteen isolates of Melampsora larici-populina originating from seven provinces or cities were investigated on the host veaction type, infectious latency and sporulation distinction host to respond the determination as well as the latent period, produced the spore quantity observation, further was clear about M. larici-populina in our country＇s physiological race differentiation. The result indicated that, in 1,5 strain 13 separately belong to 4 physiological races, Th053, Sb and Cj052 turns over to 1 physiological race CMLP1, Ts06, Gl051, Hb05-1 and Sb052 turns over to 2 physiological race CMLP2, Qh063, Gl052, Hdao and Sb05l turns over to 3 physiological race CMLF3, Bq and Qh061 turns over to 5 physiological race CMLP5, By05-3 and Zs divide into a pathogenesis group.
