【摘要】 采用国际上通用的鉴别寄主谱,对东北三省番茄叶霉病菌生理小种进行分析鉴定。采集到的33个菌株主要为生理小种1.2.3、1.2、2.3、1.2.3.4和1.2.4,其中以小种1.2.3.4为主,而且1.2.3.4和1.2.4为新发现的生理小种。在以后的育种工作中需要引入新的番茄抗叶霉病基因,以培育出抗番茄叶霉病的新品种。更多还原

【Abstract】 The physiological races of tomato leaf mold collected from the eastern three provinces were analyzed by using differential host.Among the collected 33 pathogen strains, the main physiological races were 1.2.3, 1.2, 2.3, 1.2.3.4 and 1.2.4, and 1.2.3.4 was the dominant race,1.2.3.4 and 1.2.4 were new races.New resistant genes should be introduced into tomato breeding.更多还原
