Abstract: 【Objective】 To screen buckwheat varieties(lines)suitable for different growing areas in Inner Mongolia and to meet the needs of buckwheat processing companies,as well as,to provide reference for buckwheat variety evaluation and application. 【Methods】 The AMMI model was used to analyze the stable yield and high yield of 15 buckwheat varieties(lines)in 4 pilots(the experimental site in Inner Mongolia Academy of Agricultural and Animal Husbandry Sciences,Wuchuan County of Hohhot,Guyang County of Baotou,Naiman Banner of Tongliao). 【Results】 In varince analysis,variety,experimental location and the interaction between the variety and experimental location were all extremely significant(P<0.01). According to AMMI model analysis,the interaction effect of IPCA1 and IPCA2 explained 92.28% of the variety and location interaction information which indicated the varieties and locations chosen were representative. Mengku 11,Mengku 09,Mengku 93,Mengku 13,Mengku 06 were high and stable yield varieties(lines),and Mengku 45,Mengku 66 were stable varieties with poor yield,while Mengku 87 and Mengku 53 were high yield but poor stability. Guyang County of Baotou had the highest resolution for the variety identification abilities,while Wuchuan County of Hohhot had the weakest in the 4 pilots. 【Conclusion】 Mengku 11,Mengku 09,Mengku 93,Mengku 13,Mengku 06 were suitable for large-scale cultivation in Inner Mongolia. The AMMI model could be used to accurately analyse variety stability and high yield.
