研究稻瘟病生理小种的类群及其变化,对于研究稻瘟病的流行、品种抗病性变异、抗病品种的选育和合理布局,以及综合防治的研究都有重要意义。现将1981～1982年宁夏引黄灌区稻瘟病菌生理小种研究结果报告如下。一、试验方法供试鉴别品种采用全国稻瘟病菌生理小种研究协作组筛选出的七个标准鉴别品种和三个宁夏辅助鉴别品种,即特特普、珍龙13、四丰43、东农363、关东51、合江18、丽江新团黑谷、79D-262、秋光和京引39
It is important to study the epidemic of blast, the variation of disease resistance, the breeding and rational layout of resistant varieties and the study of integrated control of the races of physiological races of rice blast. Now 1981 ~ 1982 in Ningxia Yellow River irrigated cucumber germplasm race results reported as follows. First, the test methods for the identification of the test varieties using the Chinese blast bacteria physiological races research collaboration group selected seven standard differentiated varieties and three auxiliary identification varieties in Ningxia, namely Tete Pu, Zhenlong 13, Si Fung 43, Dongnong 363, Kanto 51, Hejiang 18, Lijiang New Group Black Valley, 79D-262, Autumn Light and Beijing Lead 39
