摘要

1988~1993年在北京用采自中国4个谷子生态区白发病菌[Sclerospora graminicola(Sacc.) Schröt.]标样,以新创造的单病株(系)卵孢子菌土种子包衣接种法研究了我国粟白发病菌的生理小种。结果显示,白发病菌株与粟品种间有强互作反应,说明粟白发病菌的致病力有特异性。经选择,确定三三二、西城白、大青苗、柳条青和189等5个品种为一套适宜于测试粟白发病菌生理小种的鉴别品种。根据68个参试菌株在5个鉴别品种上的反应特征,初步将我国白发病菌区分为6群20个生理小种,并明确了各小种在各生态区的分布,我国4个谷子生态区中,黄土高原病菌小种类群最多,致病力也较强。

Abstract

During 1988~1993, 68 oospore isolates of downy mildew[Sclerospora graminicola (Sacc.) Schröt.] and 51 foxtail millet[Setaria italica (L.) P. Beauv.] germplasm from 4 cropping ecological regions of China have been collected and tested for variability and the physiological races of the pathogen.
