| 摘 要： | 由稻曲病菌（Ustilaginoidea virens）引起的病害是当前限制我国水稻优质高产的重要病害之一。家畜食用被稻曲病菌厚垣孢子污染的谷物可导致中毒。近20年来，稻曲病防治主要以喷施化学农药为主。研究品种布局对稻曲病菌群体结构的影响，有助于了解病害的发生规律及提出有效的病害防治策略。本文初步分析了稻曲病菌群体结构与水稻品种构成的关系。

| Abstract: | The genetic diversity of 110 strains of Ustilaginoidea virens from Liaoning province and Beijing where the types of rice variety constitution were different, was assessed by AFLP. The results showed that the coefficient of strains from Liaoning and Beijing was 0.92 and 0.55 respectively, and the strains from Beijing were divided into two distinct groups. There was no specific DNA pattern for the isolates from the same rice varieties, and there was no correlation between the clusters based on genetic similarity coefficient and variety origin of isolates. |
