The 25 acces-sions were classified into three major groups: A, B, and C by cluster analysis using UPGMA, which showed significant relationship with the origin regions of accessions. Thus, it was suggested that the Sichuan hulless barleys could be used as elite germplasms to enhance the genetic background for super-hulless barley breeding.

聚类分析结果表明， 25份材料可分成A、B、C 3大类，材料聚类与其来源地有明显的相关性。25份材料间的平均遗传距离较小(0.3240)，平均遗传多样性较低(0.5126)，遗传基础较为狭窄。
