摘  要：
为提高优质油份组成品种的选择效率,根据目标性状有的放矢的选配杂交亲本是前提。对中国240份北方大豆种质资源的油份及5个脂肪酸组分进行测定,通过遗传多样性、主成分和聚类分析,对其进行表型鉴定及基因型分类。结果表明,北方大豆种质油份及脂肪酸组分变异较丰富,遗传多样性程度较高。根据主成分分析,筛选到3个主成分进行聚类分析,通过聚类分析将供试种质资源分为7类。第1、6、7类群为高油群体,第3、5类群为次高油群体,第2、4类群为低油群体,7个类群间的脂肪酸组分各有差异。根据育种目标在群体间选配亲本,可提高品质育种的效率。

摘  要：
Selecting of hybrid parents according to the target traits is the premise of improving selectionefficiency of soybean cultivars with high quality oil content. The content of oil and 5 fatty acids was measuredin 240 soybean germplasm of North China. Phenotypes and genotypes were identified and classified by geneticdiversity, principle components and cluster analysis. The results showed that there were rich genetic variationand diversity for the content of oil and 5 fatty acids in 240 soybean collections in North China. According to theprinciple components analysis, three principle components were screened. Cluster analysis was conducted withthree principle components. 240 germplasm resources were divided into seven genetic groups by clusteringanalysis. Group 1, 6, 7 were high oil content cluster; Group 3, 5 were the second-rate high oil content cluster;Group 2, 4 were low oil content cluster. The fatty acids compositions showed differences among 7 groups.According to the breeding target, selecting parents from groups could improve the efficiency of breeding highqualitycultivars.
