在田间设置６品种×４小种组合的小麦条锈病隔离接种试验小区，成株期同步测定了各组合的组织学病变特征数值，包括侵入率、菌落面积、坏死面积、单菌落吸器个数和流行学特征数值，包括相对侵染点数、潜育期、病斑面积、产孢面积、孢子堆密度、病害传播速度和流行速度。计算了各品种，各项特征值的小种间变异系数和品种－小种互作方差贡献率并比较了在抗病性鉴定中利用它们估测小种专化性和非小种专化性的效果。在此基础上进行了多项指标间的相关分析。建议今后在抗病性类型鉴定中，将观察项目简化为镜检坏死面积比、单菌落吸器数或调查侵染几率、孢子堆密度等并计算这些数据的小种间变异系数来定量评价抗病性的小种专化程度
In the field, 6 stripe rust breeds were inoculated in the experimental plot of wheat stripe rust isolation inoculation, and the histological characteristics of each combination were determined simultaneously at adult stage, including invasion rate, colony area, necrotic area, number of single colony aspirate and Epidemiological characteristics include relative infestation points, incubation period, lesion area, sporulation area, spore bulk density, disease spread and prevalence. The variances of inter-subspecies variability and variances of breed-breed interactions were calculated for each breed, their eigenvalues and their contribution to the evaluation of disease resistance Effect. On this basis, a number of indicators between the correlation analysis. It is suggested that quantitative evaluation of disease resistance should be carried out in the identification of disease resistance types by reducing the observation items to the area of microscopic necrosis necrosis, the number of single colony aspirates or the investigation of infection probability and spore bulk density, and calculating the inter-species coefficient of variation Sex specialization degree
