摘　　要：选取我国69个苹果主要生产品种为实验材料,连续3a对其褐斑病和斑点病抗性进行综合评价、研究。结果表明:69个苹果主要生产品种对褐斑病和斑点病抗病性,不同的品种族系间、及同族系的不同品种间对两种病害的抗性表现出差异极显著。大多数苹果品种对两种病害表现为感病或高感,表现为抗病或中抗的品种少。其中,对褐斑病表现为抗病、中抗、感病和高感的品种分别占4.3%、24.6%、47.8%和23.2%;对斑点病表现为抗病、中抗、感病和高感的品种分别占8.7%、23.2%、43.5%和24.6%。‘秦冠’、‘甜黄魁’、‘印度(Indo)’对两种病害均具有抗性。苹果品种对两种病害的抗性相关性达到极显著水平,说明苹果对两种病害存在共同抗性因子。A 3-year study was conducted rnali in the 69 apple cultivars currently to evaluate the resistance to Marssonina coronaria and Alternaria China to sistance breeding and China apple industry. Resistances to both cant differences among 69 cultivars.

Among them, ＂Qin ce, susceptl respectively guan＇, ＇Tian resented resistant to both diseases. The correlation coefficient of resistance to both y significant, suggesting that the apples contained the common resistance genetic factors to both diseases.
