Abstract: In September 2018,a new leaf spot on Rosa chinensis with incidence of up to 60% was observed in a park in Miyun district of Beijing. Disease samples were collected and three strains（JZB3210001,JZB3210002 and JZB3210003）were obtained by isolation and single spore purification. According to the morphological characteristics,they were identified as Calonectria sp.. For molecular phylogenetic analysis,β-tub,Cal,H3,EF1-αgenes were amplified with genomic DNA of these three isolates. Phylogenetic trees... More
