摘　　要：采用涂抹法、浸蘸法、菌饼覆盖法和注射法接种苹果黑星菌分生孢子,确定了适于苹果黑星病菌的涂抹接种法。收集了"秦冠"、"陕富6号"、"嘎啦(丽嘎)"、"红星"、"乔纳金"、"粉红女士"、"金世纪"、"萌"、"太平洋玫瑰"、"澳洲青苹"、"4-1"、"M26"、"MM106"、"八棱海棠"、"新疆野苹果"等15种苹果种质资源,并对其抗苹果黑星病特性进行鉴定和评价。结果表明,15种苹果种质可被划分为高度抗病品种"新疆野苹果"和"秦冠",中度抗病品种"八棱海棠",中度感病品种"MM106"、"M26"、"乔纳金"、"红星"、"陕富6号"和"丽嘎",高度感病品种"澳洲青苹"、"4-1"、"萌"、"太平洋玫瑰"、"粉红女士"和"金世纪"4类。Spreading inoculation is confirmed as the best inoculation method for Venturia inaequalis among the spreading,soaking,fungi disk coverage and injecting methods with conidiospore suspension of V.inaequalis.15 apple cultivars including＂Qinguan＂（Malus domestica）,＂Fuji＂（M.domestica）,＂Gala＂（M.domestica）,＂Starking Delicious＂（M.domestica）,＂Jonagold＂（M.domestica）,＂Pink Lady＂（M.domestica）,＂Gold Century＂（M.domestica）,＂Gafu＂（M.domestica）,＂Pacific Rosa＂（M.domestica）,＂Granny Smith＂（M.domestica）,＂4-1＂（M.pumila）,＂M26＂（M.pumila）,＂MM106＂（M.pumila）,＂Midget Crabapple＂（M.micromalus）and＂Xinjiang Wild Apple＂（M.sieversii）were collected.Resistance of the 15 cultivars to V.inaequalis was determined through conidiospore suspension inoculation.The 15 cultivars were divided into 4 groups based on disease resistance index and average disease severity.The divisions are high resistance cultivars including ＂Xinjiang Wild Apple＂ and ＂Qinguan＂,moderate resistance cultivar including ＂Midget Crabapple＂,moderate susceptible cultivars including ＂MM106＂,＂M26＂,＂Jonagold＂,＂Starking Delicious＂,＂Fuji＂ and ＂Gala＂,and high susceptible cultivars including ＂Granny Smith＂,＂4-1＂,＂Gafu＂,＂Pacific Rosa＂,＂Pink Lady＂ and ＂Gold Century＂.
