摘　　要：研究苹帅和苹艳对早期落叶病及轮纹病的抗性,对优化新品种配套栽培技术具有重要意义。通过田间调查和接种试验,对苹果新品种苹帅和苹艳的早期落叶病及轮纹病抗性进行了研究。田间调查结果表明:苹帅和苹艳的早期落叶病及轮纹病自然发病率极低;褐斑病离体接种试验和轮纹病田间接种试验结果表明:苹帅和苹艳具有很强的褐斑病及轮纹病抗性。The resistances to early defoliation and ring rot of new apple varieties Pingshuai and Pingyan were studied by the field investigation and inoculation.The investigation results showed that the natural infection rates of early defoliation and ring rot were very low.The inoculation results showed that the two varieties had strong resistances to Marssonina mali（P.Henn.）Ito and ring rot.
