| Abstract: | To confirm the causal pathogen and damage degree of a new disease of kiwifruit-black spot in Shaanxi Province, a field investigation was conducted in Zhouzhi County and Huyi District in 2018. The pathogen was isolated from the diseased fruits and identified based on morphological characteristics, pathogenicity testing, sequence alignment and phylogenic tree analysis. The results showed that the average incidence of black spot was 65%, and the early fruiting rate was 33%. Fruits infected with black spot disease were soft-rotted after being stored for two months under low temperature conditions. The pathogenic fungi were isolated from the under skin of Cuixiang kiwifruits and the strains could produce two types of conidia, including oval α-type conidia and curved β-type conidia. Through sequences alignment of 18S rRNA, ITS, reference gene (EF1-α) and phylogenetic tree clustering analysis, it was identified for the first time that the causal pathogen causing black spot disease of Cuixiang kiwifruit in Shaanxi Province was Diaporthe eres. |
