In order to understand the genetic diversity of Citrus reticulate cv.Niurouhong germplasms,37 phenotypic traits and fruit intrinsic quality traits were selected from 24 Citrus reticulate cv.Niur-ouhong specific germplasms for genetic diversity analysis,correlation analysis,cluster analysis and principal component analysis.The results showed that the diversity of fruit traits was rich,and the variation of top shape,surface color,seed number,seed weight and single fruit weight was higher.Correlation analysis showed that there was significant positive correlation between fruit phenotypes,but significant negative correlation with soluble solids and titrable acid content.24 Citrus reticulate cv.Niurouhong germplasms were divided into two categories by cluster analysis,which could be used as breeding materials for fruit appearance quality and internal quality,respectively.The cumulative contribution rate of the first 5 principal components was 82.257％.
