Abstract: 【Objective】To investigate the stability and adaptability of potato varieties(lines)in Midwestern Inner Mongolia′s primary production zones,as well as the possibility of using the AMMI model to assess the stability and adaptability of varieties(lines)in this area.【Methods】The AMMI model was used to assess the stability and adaptability of 13 potato varieties(lines)in four trial sites,Chengguan Town in Horinger County of Hohhot,Kezhen Town in Wuchuan County,Jining District in Ulanqab City,and Jinshan Town in Guyang County of Baotou City.【Results】The AMMI model′s principal component values(IPCA1,IPCA2)could explain 86.37% of the entire interaction′s sum of squares. Jin 1021-5 with a yield of 41 954.30 kg/hm2 and variety stability parameter of 1.649 3,was a high yield and stable yield line. D860,BF1020.1 and Jin 0905-14 with good yield but higher stability parameter,making them suitable for specific planting regions. The yield stability of BF0743.13 was good,however the yield was poor. The resolution of the four pilot sites were Horinger(E1)>Jining(E3)>Wuchuan(E2)>Guyang(E4),and the environmental resolution parameters were 5.857 6,5.028 8,4.990 6 and 3.221 4 respectively. Horinger(E1)had the highest variety selectivity,whereas Guyang(E4)had the lowest variety selectivity.【Conclusion】Jin 1021-5 had a high yield and good stability,making it a good candidate for spreading in Midwestern Inner Mongolia. The AMMI model was a good fit for the experimental data. It could accurately analyze and identify the high yield,stable yield,and adaptability of potato varieties(lines)when combined with the double plot and stability parameters.
