为综合分析甘肃省啤酒大麦品种的丰产性、稳产性和适应性，应用Genstat的GGE双标图对2017年甘肃省联合区试9个啤酒大麦品种(系)在5个参试地点的产量进行分析。结果表明，适应性较好的品种(系)是0520-34、Z06-278-9、2153122；丰产性和稳产性较好的品种(系)是0521-6、Z06-278-9、甘啤6号，0520-23的丰产性、稳产性和适应性均较差。Z06-278-9是所有参试品种(系)中最具推广潜力的理想品种。GGE双标图为评价新品种的丰产性、稳产性和适应性提供了一个更加科学有效的方法。

In order to analysis the high and stable yielding ability and adaptability of the tested cultivars in the beer barley regional trials， the GGE-biplot was employed to analysis nine cultivars from five regions on grain yield in the beer barley regional trial of Gansu Province in 2017. The results showed the cultivars of 0520-34， Z06-278-9 and 2153122 had a higher adaptability than other cultivars. 0521-6， Z06-278-9 and Ganpi 6 performed well in high and stable yielding ability. 0520-23 was poor in high and stable yielding ability and adaptability of the tested cultivars. Z06-278-9 was the ideal cultivar with the most promotion potential among all the cultivars tested. GGE-plot provide a scientific and effective method for objective evaluation of the high yield， adaptability and stability of barley cultivars.
