    Abstract:

    To understand sepal trait diversity and their impact on fruit appearance， this study investigated the diversity， correlation and clustering analysis of sepal traits in 200 pear germplasm resources. Results showed a U-shaped distribution of calyx abscission rates， with higher number of germplasm resources in extremely high and low rate groups. The sepal development process was divided into three stages： before （2-4 days after flowering）， during （5-7 days after flowering）， and after （8-10 days after flowering） abscission zone formation. Persistent and residue calyx germplasm resources exhibited aggregated and upright calyx postures. In Oriental Pear （including Pyrus bretshneideri Rehd.， P.ussuriensis Max.， P.pyrifolia Nakai， P. sinkiangensis Yü， hybrid breeding varieties ）， calyx-shedding fruit generally has no calyx convex， and the calyx convex on the persistent calyx fruit has little effect on fruit shape. The thickness and area of sepals varied greatly among different germplasm resources， although these characters did not reveal effect on fruit shape. Among 14 germplasms of P. communis L.， sepals are generally thin and small， with little effect on fruit shape. Analysis of persistent calyx abnormal fruit identified 33 varieties with varying degrees of abnormality， mainly oblique and protruding calyx fruit. The residual calyx abnormal fruit was oblique， indicating that sepal appearance affects fruit shape but is not the sole factor. Correlation analysis found extremely significant negative correlations between calyx abscission rates and calyx convexity. Cluster analysis divided these germplasm resources into four categories mainly based on calyx shedding rate （80.7%-100.0%， 16.6%-40.2%， 45.5%-78.5%， 0-11.9%）. These findings provide a reference for pear germplasm resource utilization and variety breeding.
