摘　　要：试验对‘Гресия’、‘Глесия’、‘B10-2020’、‘BGL-2019’和‘BLG-2019’ 5个工业大麻品种(系)的6个产量性状、4个品质性状以及7个农艺性状进行相关性和主成分分析,结果表明,通过产量、农艺性状相关性分析得出茎粗、工艺长度与鲜皮重、干皮重、鲜茎重等产量性状之间普遍呈显著正相关;同时,通过主成分分析从14个性状指标中提取出3个主成分,累积贡献率为90.20%,根据综合评分,得出不同品种(系)综合性状排名为‘B10-2020’>‘Гресия’>‘Глесия’>‘BLG-2019’>‘BGL-2019’,相关性分析显示综合得分与大部分农艺性状显著正相关,与品质性状显著负相关,表明综合得分可以较好地反映5个试验品种的综合表现情况,为培育、开发高产量及高品质工业大麻纤维提供参考。The experiment conducted correlation and principal component analysis on six yield traits,four quality traits and seven agronomic traits of five industrial hemp varieties(lines)including‘Гресия’,‘Глесия’,‘B10-2020’,‘BGL-2019’and‘BLG-2019’.The results showed that through the analysis of the correlation between yield and agronomic traits,there was a significant positive correlation between stem thickness,process length,and yield traits such as fresh bark weight,dry bark weight,and fresh stem weight.At the same time,three principal components were extracted from 14 trait indicators through principal component analysis,with a cumulative contribution rate of 90.20%.According to the comprehensive factor F,the comprehensive traits of different varieties(lines)were ranked as‘B10-2020’>‘Гресия’>‘Глесия’>‘BLG-2019’>‘BGL-2019’.The correlation analysis showed that the comprehensive score was significantly positively correlated with most agronomic traits but signifiantly negatively correlated with quality traits,indicating that the comprehensive score could better reflect the comprehensive performance of the five varieties,providing a reference for breeding and developing high-yield and high-quality industrial hemp fibes.
