为筛选适宜在高寒阴湿区种植的优良蚕豆品种，以青蚕13、青蚕14和青蚕25为供试材料，分析不同蚕豆品种形态特征及产量差异，采用相关性分析和主成分分析进一步明确品种的适宜性。结果表明，青蚕13和青蚕25的单株重、单株粒数、单株粒重、单株荚重、荚数均显著高于青蚕14；青蚕13和青蚕25的生态适宜性较强，其鲜产量分别比青蚕14高1 974.30、1 453.95 kg/hm2。青蚕13和青蚕25在甘肃省高寒阴湿区产量高、收益好，宜在该地区推广种植。

To select excellent Vicia faba varieties suitable for planting in alpine humid areas, high-yielding varieties Qingcan 13, Qingcan 14, and Qingcan 25 were used as test materials. Morphological characteristics and yield differences of different Vicia faba varieties were analyzed, and correlation analysis and principal component analysis were used to further determine the suitability of the varieties. The results showed that Qingcan 13 and Qingcan 25 had significantly higher weight per plant, kernel number per plant, kernel weight per plant, pod weight per plant, and pod number per plant compared to Qingcan 14. Qingcan 13 and Qingcan 25 exhibited strong ecological suitability, with fresh yields 1,974.30 kg/ha and 1,453.95 kg/ha higher than Qingcan 14, respectively. Qingcan 13 and Qingcan 25 are high-yielding and profitable in the high cold and humid areas of Gansu Province, and are suitable for promotion in these areas.
