摘要： 1986-1988年秋季, 在天津市郊区3个地点采集菜豆锈病菌夏孢子, 经在感病品种锦州双季豆上两次单夏孢子分离后, 再在4个鉴别品种上分离鉴定, 获得锈病菌分离物, 最后采用19个国际通用鉴别品种进行锈菌生理小种鉴定。结果表明, 天津地区菜豆锈病菌存在两个主要生理小种。这两个小种在鉴别品种Olatne、51051、AXS37、30-7-2上发病等级为3、1、3、2和1、1、3、2。经与Stavely鉴定出来的美国38-57号小种比较, 无一相同。因此, 暂把3、1、3、2 定为CTJ-1（中国天津一号）, 把1、1、3、2定为CTJ-2（中国天津二号）小种。

Abstract: Collecting urediniospores of Uromyces phaseoli(Pers.) Wint in three sites of Tianjin’s suburb in autumn from 1986 to 1988. Single-uredinial isolates was made twice in susceptible cultivar"Jin-Zhou Shuang Ji Don", then was identified in four cultivars to attain pure isolates. And finally, identified by 19 different bean cultivars commonly used by most countries. The results showed that two main physiological races existed in Tianjin. Their grades of diseases happened on cultivars Olatne, 51051, AXS37, 30-7-2 were 3, 1, 3, 2 and 1, 1, 3, 2 respectively. These two races were different from American race No. 37-53 iedntified by Stavely Race 1, 1, 3, 2 was temporarily named as C. T. J-1(No.1 Tianjin, China) ana race 3, 1, 3, 2 as C. T. J-2(No.2 Tianjin, China). The result showed that two main physiological races existed in Tianjin. Their grades of diseases happened on identified cultivar Olatne, 51051, AXS37, 30-7-2 were 3, 1, 3, 2, and 1, 1, 3, 2. respectively. Comparing with No. 37-58 races of American that is identified by Stavely, no one is the same. So we name temporarily 1, 1, 3, 2 as C. T. J-1(No. l Tianjin, China) and 3, 1, 3, 2 as C. T. J-2(No.2 Tianjin, China), rcspeectively.
