Abstract: 【Objective】 The purpose of this study was to analyze and screen the bent peduncle phenotypic traits of cut rose，and comprehensively evaluate the bent peduncle characteristics of different varieties of cut rose，so as to provide reference for correcting different types of cut rose bent peduncle and promoting the high quality and efficient production of cut rose. 【Method】 Ten cut rose varieties cultivated in greenhouse were studied，and the bent peduncle rate of different varieties was calculated. The 12 phenotypic characters such as flower width，flower height and sepal fall distance were determined in bent peduncle plants，and the coefficient of variation（CV）of each index was counted. Principal component analysis（PCA）and cluster analysis were used to evaluate the bent peduncle characteristics of 10 cut rose varieties. 【Result】 The cut rose variety Gotcha had the highest bent peduncle rate（16.19%），and the White O’Hara had the lowest bent peduncle rate（3.44%）. There were 3 and 2 change types of Glamorous and Awakening after bent peduncle sepals fell respectively，and 1 in other varieties. The CV of 10 phenotypic traits，such as fresh flower weight，was greater than 10.00%， and there was no specific orientation in the bent peduncle direction of each variety. Among the 12 phenotypic traits tested， 5 pairs were extremely significantly correlated with each other（P<0.01）and 5 pairs were significantly correlated with each other（P<0.05）. The results of PCA showed that stem diameter，maximum petal thickness，flower fresh weight， petal number，flower width，distance from disk to the first leaf，fresh weight of falling sepal and height of peduncle were the 8 key indicators for evaluating the characteristics of the bent peduncle since they had large load. According to the membership function method，the comprehensive evaluation value（D）was ranked as Gotcha > Romantic Beach > Jumilia > Summer Love > Goddess of the Luo River > Pink O’Hara > Awakening > Glamorous+ > Juliet > White O’Hara. The cluster analysis results showed that the cut rose varieties in the test could be divided into 3 groups，Gotcha，Romantic Beach and Jumilia had outstanding bent peduncle characteristics with D greater than 0.650. 【Conclusion】 The variation of phenotypic characters of 10 cut rose varieties with bent peduncle plant is great. The phenotypes of sepals in Glamorous+ and Awakening bent peduncle have more changes. Eight key indexes，including stem diameter，maximum petal thickness， flower fresh weight，petal number，flower width，distance from disk to the first leaf，fresh weight of falling sepal and peduncle height，are selected to evaluate the characteristics of rose bent peduncle. Three cut rose varieties with strong bent peduncle characteristics，Gotcha，Romantic Beach and Jumilia，are obtained，which can be used as materials to study the bent peduncle characteristics of cut rose.
