摘　　要：月季(Rosa chinensis Jacq.)是蔷薇科蔷薇属的世界著名花卉,有“花中皇后”的美称,其品种众多,花大艳丽、花色多样、且有怡人的香味和不分季节持续开花的性状,寓意着美好,历来深受世界各国人民的喜爱[1]。在中国,月季被很多城市定义为市花,在园林绿化景观中被广泛应用,但在栽培过程中,极易受到病虫危害,出现一些诸如斑点、发黄、落叶、萎蔫、甚至死亡。月季病虫害不仅影响月季的观赏效果,还降低月季的经济价值[2]。In 2021,typical leaf samples of Rosa chinensis black spot disease were collected from the South Tropical Garden in Kunming,Yunnan Province,China,and a strains were obtained by tissue isolation method.According to Koch's rule,morphological characteristics and phylogenetic analysis of ITS,TEFl and TUB gene sequences,the pathogen was identified as Gnomoniopsis rosae.This is the first report that G.rosae caused R.chinensis black spot disease in China.
