摘要: 为了解决甜菜褐斑病病防治问题,2009—2016年,对黑龙江省10个地区166个甜菜品种,采取田间调查发病率的方法进行分类研究。将地区分为轻病区、中病区和重病区3类;将品种的抗性水平分为高抗、抗病、中抗、中感、感病、高感6个级别:甜菜褐斑病病情指数(DI)≤15的地区为轻病区,15

Abstract: The paper aims at the prevention and control of Cercospora leaf spot (CLS) of sugarbeet. The disease index (DI) of 166 sugarbeet varieties were investigated by field test in 10 regions of Heilongjiang from 2009 to 2016. The results showed that: the regions were divided into 3 disease areas as light, middle and heavy areas; the resistance levels of the varieties were divided into 6 levels, including high resistant, resistant, middle resistant, medium sensitive, sensitive and high sensitive varieties; the area with the disease index (DI) less than 15 was light disease area, 1530 was the heavy disease area; high resistance varieties had DI≤20, resistant varieties had 20
