Abstract: Taking ‘Longxiang’ pear as the test material, correlation analysis, cluster analysis, and diversity analysis were used to study 18 traits of fruit quality, seed length, and titratable acidity.In order to clarify the differences and correlations in fruit traits among hybrid offspring, and to screen superior plant lines with better quality based on target traits.The results showed that among the 12 described traits, the highest diversity index was calyx depression depth（0.717 6）,and the highest variation coefficient was chlorophyll a（65.02%） among the 18 quantitative traits.There was a significant positive correlation between fruit weight and fruit appearance, and a significant negative correlation between titrable acid and solid acid ratio.Ten excellent lines were selected by cluster analysis and principal component analysis, which provided the reference basis for early screening.
