大豆叶烧病(Xanthomonas phaseoli var. sojensis)是一种细菌性病害。据报导,美国,巴西、印度、苏联等国家均有此病发生,美同南部湿度大的地区发病尤为严重,我国东北、华北以及华中地区亦有此病发生,1980年湖北省大豆叶烧病十分严重,著者在本所试验场的观察研究结果,大豆开花前后(武汉地区7—8月)连续阴雨,低温寡照是此病害发展的适宜条件;叶烧病对大豆产量、品质均有较大影响;不同品种的感病程度有很大差异。这种差异与种皮色、原产地以及生育期有一定关系。通过品种资源的抗病性研究,将有可能为大豆生产和大豆育种工作提供抗病(叶烧病)种质资源。
Soybean leaf fever (Xanthomonas phaseoli var. Sojensis) is a bacterial disease. It is reported that the United States, Brazil, India, the Soviet Union and other countries have the disease occurred in the United States with high humidity in southern parts of the incidence is particularly serious, China’s northeast, north China and central China also have the disease occurred in 1980 in Hubei Province soybean leaf fever Very serious, the author observed in our field test results before and after the flowering of soybean (Wuhan July -7 months) continuous rainy weather, low temperature is the appropriate conditions for the development of this disease; leaf blight on the yield and quality of soybeans are larger Affect; different varieties of the degree of illness are very different. This difference with the seed coat color, origin and growth period have a certain relationship. Through the study of the disease resistance of varieties and resources, it will be possible to provide disease-resistant (leaf-burn) germplasm resources for soybean production and soybean breeding.
