贵州马铃薯炭疽病的诊断及病原鉴定

Diagnosis and Identification of Potato Black Dot in Guizhou

为准确鉴别马铃薯炭疽病症状及病原菌种类,采用形态学观察、ITS序列分析鉴定和分子系统学相结合的方法对贵州省内马铃薯炭疽病病株进行病原菌的分离与鉴定。结果表明:该病原菌为球炭疽菌(Colletotrichum coccodes)。目前,在省内是首次对该病原进行准确鉴定和报道。

In order to provide references for actually identify the symptom and pathogenic bacteria species of potato black dot, the pathogenic bacteria were isolated and identified by using methods of morphological observation, ITS sequence analysis and molecular systematics. Results： The pathogen was Colletotrichum coccodes, which was firstly identified and reported in Guizhou.
