摘　　要：猕猴桃为猕猴桃科(Actinidiaceae)猕猴桃属(Actinidia)多年生落叶藤本果树。猕猴桃营养丰富、风味独特,是当今世界新兴水果之一。江西省奉新县是我国猕猴桃主要产地之一,近年来,随着其种植规模的不断扩大,猕猴桃病害问题也日趋凸显[1]。2021年9月,该县山口基地有0.2公顷“金艳”猕猴桃发生炭疽病,全园多点发病,一些重病株病叶率超过70%,并出现大量落叶,对猕猴桃产量和品质造成严重影响。In September 2021,a foliar anthracnose disease of kiwifruit was observed in Shankou base,Fengxin County,Jiangxi Province.Isolation were performed for the infected leaf tissues with the conventional tissue isolation method.On the basis of morphological characteristics,pathogenicity test and analysis of the combined sequence data of rDNA-ITS,TUB2 and CAL genes,the isolates were identified as Colletotrichum fructicola.To our knowledge,this is the first report of C.fructicola causing anthracnose of kiwifruit both in China and abroad.
