Abstract:

【Objective】 In order to determine the types of potato diseases and pathogenic bacteria in the different potato producing areas along the Tianshan Mountains of the north of Xinjiang, the susceptible plants and tubers were collected from Qitai farm, Nileke experimental station, Shirenzi village of Balikun, in Xinjiang Uygur Autonomous Region. 【Methods】 The tissue isolation method,the morphological identification, 16S rDNA and ITS sequence analysis, specific primer amplification and Koch's pathogenicity tests were applied to study the isolates. 【Results】 The results showed that the pathogens were Pseudomonas lactis, Fusarium oxysporum, Fusarium solani, Alternaria sp., Alternaria tenuissima, Alternaria alternata, and Geomycetes candidum, causing bacterial wilt, dry rot, early blight, black spot, red star, white mildew tuber of potato diseases, the pathogenicity of Fusarium oxysporum was stronger among of them. 【Conclusion】 In this study, the potato diseases are identified as blight, dry rot, early blight in these producing areas of Xinjiang. And bacterial wilt, dry rot of white mildew, red star disease, black spot disease.

Key words: Xinjiang potato disease; pathogens; isolation and identification; pathogenicity

摘要：

【目的】研究新疆北部沿天山主要种植区马铃薯病害种类以及病原菌的种类,采集奇台农场、尼勒克县实验站、巴里坤石人子村等地区的感病植株与块茎分离鉴定。【方法】采用组织分离法结合显微形态观察、柯赫氏法则、16S rDNA及ITS鉴定方法,分离鉴定引起马铃薯病害的病原菌。【结果】病原菌有假单胞菌(Pseudomonas lactis)、致病性尖孢镰刀菌(Fusarium oxysporum)、茄病镰刀菌(Fusarium solani)、链格孢菌(Alternaria sp.)、细级链格孢菌(Alternaria tenuissima)、赤星病菌(Alternaria alternata)、白地霉(Galactomyces candidum),分别引起青枯病、枯萎病、干腐病、早疫病、黑斑病、赤星病、白地霉干腐病,其中致病性尖孢镰刀菌(Fusarium oxysporum)致病性较强。【结论】新疆马铃薯主产区的病害有枯萎病、干腐病、早疫病,并且青枯病、白地霉干腐病、赤星病、黑斑病。
