以16个南通扁豆品种为试材，采用主成分和聚类分析方法对10个主要农艺性状进行分析，探讨影响扁豆产量的主要因子及品种间的遗传距离。结果表明：在保留84.8893%信息量的前提下，10个农艺性状可简化为粒型因子、粒重因子Ⅰ、荚型因子和粒重因子Ⅱ等4个主成分，在育种过程中需结合育种目标确定合理的主成分值；16个品种间的遗传距离为0.8866～7.7757，平均4.0474；16个品种可分为4类，荚色与地理来源不能作为判断种质间遗传差异的依据。

Taking 16 cultivars of Nantong lentils 〔Lablab purpureus (L.) Sweet〕as experimental material, we analyzed the principal components of 10 major agronomic traits using principal component analysis and cluster analysis to investigate the genetic distance and the main factors affecting yield of lentils.The results showed that under the premise of keeping 84.889 3% of information amount,10 agronomic traits could be simplified as the following 4 principal components:grain type factor,grain weight factorⅠ,pod type factor and grain weight factorⅡ.During the breeding process,the reasonable principal component values should be determined combining with the breeding objectives.The genetic distances between these 16 varieties were 0.886 6-7.775 7, and the average was 4.047 4.These 16 varieties could be divided into 4 classes,pod color and geographical source could not be used as the basis for judging germplasm genetic differences.
