摘　　要：为充分挖掘和利用大豆优势种质资源,本研究对60份大豆种质资源的13个表型性状进行相关性、主成分、聚类分析,建立大豆种质资源评价模型,并综合评价60份品种资源在黑龙江省西部地区的适应性。结果表明:通过相关性、主成分分析,剔除了与其他指标相关关系不大的叶形和花色,其余11个指标浓缩为4个主因子,分别为产量因子、品质因子、高度因子和倒伏因子,并提供了原性状80.92%的信息量;聚类分析将60份大豆种质资源分为4大类群,其中第Ⅲ、第Ⅳ类在黑龙江省西部地区综合表现较好;综合排序结果显示合农144、绥农69、合农65这3个品种表现最好,建议加强推广利用。In order to fully exploit and utilize the advantages of soybean germplasm resources,this study conducted correlation,principal component analysis and cluster analysis on 13 phenotypic traits of 60 soybean germplasm resources,established the evaluation model of soybean germplasm resources,and comprehensively evaluated the adaptability of 60 varieties in the western region of Heilongjiang Province.The results showed that through correlation and principal component analysis,the leaf shape and flower color which had little correlation with other indicators were eliminated,and the 11 indicators were concentrated into 4 principal factors,which were yield factor,quality factor,height factor and lodging factor,and provided 80.92%information of the original traits.Cluster analysis showed that 60 soybean germplasm resources were divided into 4 groups,and the third and fourth groups had better comprehensive performance in the western region of Heilongjiang Province.The comprehensive ranking results showed that the three varieties of Henong 144,Suinong 69 and Henong 65 performed the best,and it was suggested to strengthen the promotion and utilization of these varieties.
