Abstract
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.关键词
