摘　　要：【目的】明确甘肃省苹果煤污病的发生情况及其菌体类型的组成情况.【方法】在甘肃省主要苹果种植区进行苹果煤污病的发生情况的调查,并观察分析甘肃省不同地区果皮表面苹果煤污病的菌体类型.【结果】甘肃省苹果煤污病发生普遍,在各苹果种植区均有发生;且菌体类型具有丰富的多样性,7种菌体类型均有发生,分别是:蝇粪型点状、紧凑型点状、离散型点状、煤烟状、蜂巢状、分支状和刻点状.【结论】总体上,分枝状、刻点状和离散型点状是甘肃省分布最广泛、最常见的3种菌体类型,但甘肃省不同地区苹果煤污病的菌体类型组成存在一定差异.【Objective】To be clear the occurrence of apple sooty blotch and flyspeck（SBFS）in Gansu province and composition of mycelia.【Method】The occurrence of SBFS was investigated in main applegrowing areas in Gansu to analyze mycelial types of SBFS on apple skin.【Result】Apple SBFS occurred widely in surveyed areas.Mycelial types of apple SBFS showed high diversity,the seven mycelial types were found,including flyspeck,compact speck,discrete speck,fuliginous,ridged honeycomb,ramose and punctate.【Conclusion】Ramose,punctate and discrete speck were generally the most widely distributed and common SBFS mycelial types in Gansu.Mycelial types of apple SBFS differed within regions in Gansu.
