Diversity analysis of lateral branch traits among different Paeonia lactiflora Pall.varieties
Paeonia lactiflora Pall.is an emerging high-end cut flower in the international market in recent years,and the presence or absence of lateral branches is one of the important standards for measuring the quality of cut peony flowers.This study divided 188 Paeonia lactiflora Pall.varieties into four types based on the total number of lateral branches per plant:multi lateral branches,medium lateral branches,few lateral branches,and no lateral branches.Each type of lateral branch accounted for 4.79％,28.72％,26.60％and 39.89％of the total number of varieties,respectively.The variation range of the total number of lateral branches for multi lateral branch,medium lateral branch,and few lateral branch types was 9.00-20.00,3.00-7.00 and 1.00-2.00,respectively.Further diversity analysis of lateral branch traits showed that there were significant differences in lateral branch traits among all tested varieties and the three types of lateral branch varieties,indicating a high level of genetic diversity.The number of main branches with lateral branches and the average number of lateral branches on a single main branch are closely related to the total number of lateral branches,and are the two main factors affecting the classification of lateral branches.The results of this study can provide a variety resource reserve for the production of cut peony flowers in China.
