Abstract:

The purpose is to apply principal component analysis and cluster analysis to analyze and identify Citri grandis exocarpium germplasm resources in macro and micro level, and provide a basis for identifying, evaluating, protecting, developing and utilizing Citri grandis exocarpium germplasm resources. SPSS 19.0 was used to analyze the variability and principal components of 17 major botanical quantitative trait indexes and 6 physical and chemical indexes of Citri grandis exocarpium germplasm resources, MEGA7 was used to conduct the cluster analysis based on the SNP results. It is found that different Citri grandis exocarpium germplasm resources vary significantly in effective components, flower and leaf traits; and there are 6 main component factors including flavonoid factor and fruit shape factor and 12 influential indicators including naringin, total flavonoids and pistil thickness; germplasm resources are clustered into 2 categories and each has its own characteristics.

Key words: Citri grandis exocarpium, germplasm resources, principal component analysis, cluster analysis, evaluation
