通过对124份绿肥箭筈豌豆种质资源品种产量性状指标进行主成分分析及聚类分析。结果表明,第3主成分(荚果数)偏高,第1主成分(株高)偏低,第2主成分(分枝数)适中,箭筈豌豆种子产量较高;第1,2主成分偏高,第3主成分偏低,即株高高,分枝数多的材料,干草产量高,可作为绿肥和饲用作物材料。聚类分析可综合评价箭筈豌豆的表现,发掘产量性状突出的材料,对于箭筈豌豆的育种具有重要的现实意义。
Based on the principal component analysis and cluster analysis of yield traits of 124 green pea germplasm resources, The results showed that the third principal component (pod number) was high, the first principal component (plant height) was low, the second principal component (branch number) was moderate, and the yield of arrowhead pea seeds was higher. The first and second principal components High, the third main component is low, that is, the plant height is high, the number of branches, hay yield, can be used as green manure and feed crop material. Cluster analysis can comprehensively evaluate the performance of arrowroot pea and find the material with prominent yield traits, which is of great practical significance for the breeding of arrowroot pea.
