In order to get the best core collection, the 20 kinds of different sampling strategy was compared, including one kind of Grouping principle, five kinds of overall sampling ratios and four kinds of sampling strategies from each group, using 332 varieties from the Shandong province, which are classified as 22 types based on agronomic and morphological characters. It was found that retained ratio of phenotypic retained was not have a notable increase when the overall sampling ratio creased from 15% to 25 % . It was showed that 15% was the optimal overall sampling ratios for the tree peony core collection of Shandong province. The optimal sampling strategy was the S strategy. There were 60 varieties of Tree peony core collection was set up including 50 varieties which was screened as core collection from 332 varieties of Tree peony and 10 varieties of rare materials or elite by hand.
