大豆病毒病是大豆的主要病害之一,其中花叶病几乎伴随大豆生长而发生,危害严重。但其症状表现复杂,对病情严重度调查和品种抗性鉴定较为困难。为正确比较和评价现有品种在生产、育种中的利用价值和保产效益,探讨品种抗病性指标,需了解病指与产量损失的相关性,本文就1982～1983年有关试验结果加以阐述。
Soybean virus disease is one of the main diseases of soybean, in which Mosaic disease occurs with the growth of soybean, which is serious. However, its symptoms are complicated and the investigation of the severity of the disease and the identification of varieties of resistance are more difficult. In order to correctly compare and evaluate the utilization value and yield efficiency of existing varieties in production and breeding, and to explore the index of disease resistance of varieties, we need to know the correlation between the pathological index and the yield loss. This paper elaborates the related test results from 1982 to 1983 .
