| 摘 要： | 2011-2013年对新疆伊犁地区甜菜褐斑病发生情况进行了调查，试验依据田间自然发病的抗性分析方法，对35个品种（品系）进行了抗性分析，发现发病前期有24个品种（品系）表现为中抗，占供试品种的68.57%，其余均表现感病。但在病害高峰期该24个品种（品系）抗性发生变化表现为感病，其余11个品种抗性变化不明显仍表现感病。35个品种在病害高峰期时均表现为感病，但部分品种的病情指数之间有显著性差异，表现为高感和中感。

| Abstract: | Thirty-five sugarbeet varieties （strains） were investigated to analysize leafspot resistance in Xinjiang Yili area from 2011 to 2013. The results showed that there were 24 varieties of leafspot resistance in early period, accounting for 68.57% of all tested varieties. But in peak time of the disease, the 24 varieties （strains） were susceptible to disease and the other 11 varieties also were susceptible. The total 35 varieties showed susceptible （high sensitivity or moderate susceptible） at the peak of the disease. |
