Abstract: In order to accurately evaluate the high-yield, stable yield, and ecological adaptability of the new varieties of Fagopyrum tataricum, the AMMI model and GGE double label map were used to analyze the mprehensively evaluate the high-yield, stable yield, and pilot representativeness of five Fagopyrum tataricum varieties in six counties（districts） of semi-arid areas, semi-arid prone areas, and central arid zones in southern Ningxia. By analyzed the stability（Dg） of principal component PCA and ariety, as well as the yield stability（De） of experimental points, suitable varieties with high yield stability and good adaptability for planting in the southern mountainous areas of Ningxia were selected as Jinkuqiao 2 and Chuanqiao 3.The yield of Jinkuqiao 2 was 1 671-2 593 kg·ha^-1, with an average increase of 17.3% compared to the control variety. The yield of Chuanqiao 3 was 1 474-2 513 kg·ha^-1, with an average increase of 7.5% compared to the control variety.The experimental sites were ideal for Haiyuan County, which represents the semi-arid and drought prone areas, Tongxin County in the central arid zone, and Xiji County in the semi-arid areas.The experiment went through drought years, normal years, and flood years and the tested varieties experienced a 28.0%—45.3% reduction in yield compared to flood years in drought years.
