小麦叶锈病是小麦生产上常见的一种病害.在三种锈病中,其为害程度虽略次于条、秆锈病,但发生分布甚为普遍,我省各地历年来经常发生,在气候条件适宜的年份,造成显著的减产,尤其是我省大多数小麦品种对叶锈病缺乏抗性,一旦条件适宜便会发病,给生产带来很大损失,近年来该病又有加重危害的趋势.为了加速选育推广抗病良种,给育种和生产部门提供科学依据,1975-1980年,我们和有关单位协作,对来自省内外有关单位的几百个小麦品种和 Wheat leaf rust is a common disease in wheat production.In the three kinds of rust disease, although the degree of damage is slightly inferior to the stripe rust, but the distribution is very common throughout the province over the years often occur in the climatic conditions Of the year, resulting in significant yield reduction, especially in most wheat varieties in our province lack of resistance to leaf rust, once the conditions are suitable will be the incidence of great losses to the production in recent years the disease has aggravated the trend of harm. Accelerate breeding and promotion of disease-resistant varieties, to provide scientific basis for breeding and production sector, 1975-1980, we collaborate with the relevant units, from the relevant units within and outside the province hundreds of wheat varieties and
