摘　　要：以新引进的10个马铃薯品种为试验材料,采用高稳系数法、灰色关联系数法,通过综合评价指数对产量、产量性状及生态适应性等指标进行综合评价,以期为黄土高原丘陵沟壑区马铃薯的筛选推广提供理论依据。结果表明,2021—2022年,青薯9号、陇薯15号、甘农薯9号和陇薯10号具有丰产稳产性,V7、丽薯6号、大西洋和陇薯7号产量较低。通过灰色关联系数法分析发现,青薯9号、甘农薯9号2个品种生态适应性最强,表现稳定。综合评价表明,甘农薯9号、青薯9号、陇薯15号和陇薯10号产量及产量构成合理、生态适应性强、品质高,是适宜当地推广的优质马铃薯品种。In order to provide a theoretical basis for variety selection and new variety promotion of potatoes in the hilly and gully areas of the Loess Plateau,using 10 newly introduced potato varieties as experimental materials,a comprehensive evaluation index was used to analyze and evaluate yield,yield traits,and ecological adaptability indicators based on the high stability coefficient method and grey correlation coefficient method.Results showed that from 2021 to 2022,Qingshu 9,Longshu 15,Gannongshu 9,and Longshu 10 showed high and stable yield,while V7,Lishu 6,Atlantic,and Longshu 7 varieties had poor yield.Through the grey correlation coefficient method,it was found that Qingshu 9 and Gannongshu 9 had the strongest ecological adaptability and stable performance.Through comprehensive analysis of 10 newly introduced potato varieties,it was found that Gannongshu 9,Qingshu 9,Longshu 15 and Longshu 10 were potato varieties suitable for local promotion with reasonable yield and yield composition,strong ecological adaptability,and high quality.
