Abstract：In order to screen for high-yield,stable-yield varieties suitable for production in Hunan province,six potato va-rieties were used as test materials in three years from 2018 to 2020 and observed the phenological period,plant and tuber appearance traits,main agronomic and yield traits in the field.The stability,high-yield and adaptability of the cultivars were analyzed using two factor analysis of variance and GGE-Biplot.The results showed that the appearance and main ag-ronomic traits among different cultivars were significant differences.The contribution degree of the impact on yield relat-ed traits of varieties is environment＞genotype＞genotype environment interaction.When evaluating the fresh potato yield,plant height,number of potatoes per plant,and dry matter rate of variety,the interaction effect between genotype and envi-ronment should be fully considered.One new variety(Huashu No.1)with outstanding high and stable yield performance was screened out by GGE-Biplot analysis,which was suitable for further demonstration and promotion in this region.
