摘　　要：以北京地区主栽的‘红颜’、‘枥乙女’和‘章姬’草莓品种为试材,根据草莓种质资源描述规范和数据标准,分析了3个草莓品种的形态指标、感白粉病情况及产量等方面的差异。结果表明:‘枥乙女’的感病率、最高感病等级和病情指数均低于‘红颜’和‘章姬’,其抗白粉病能力最强,故选种‘枥乙女’品种,可以有效降低草莓白粉病的病情指数,为实现优质的草莓栽培技术提供理论依据。The main cuhivars of strawberries including ＇Akihime;, ＇Toyonoka ; and ＇Benihoppe＇ were used as the test materials in Beijing. The differences of morphological indicators, resistance to the powdery mildew and the yield were analyzed in accordance with the description norms of the germplasm and standards data of three strawberries cultivars. The results showed that the infection rate, the highest level of infection and the infection index of ＇Toyonoka ＇ were lower than that of ＇Akihime＇ and that of ＇Benihoppe＇. ＇Toyonoka＇ had the strongest resistance to the powdery mildew and would effectively reduce the infection index, and provide a theoretical basis for high-quality cultivation techniques of strawberry.
