摘要：

牡丹为芍药属(Paeonia)牡丹组(Sect. Moutan)植物，是中国栽培历史悠久的传统名花，花色、花型多样且品种繁多；伊藤杂种(P. Itoh Group)为芍药属的牡丹组和芍药组(Sect. Paeonia)组间杂交后育成的品种群。复色是一种特殊的花色呈色类型，牡丹和伊藤杂种复色品种丰富，现有的花色分类无法全面描述复色品种的花色特征。笔者经实地调查，结合文献分析，将2个类群中复色品种的花色分为单株复色、单花复色、花期复色3类，其中单花复色分6种类型。牡丹品种复色类型丰富，尤其是西北牡丹品种群中复色品种较多；伊藤杂种复色品种占比大，以渐变复色类型为主，少数品种兼具条纹、斑点和单株复色等多种类型。本文提出了新的牡丹与伊藤杂种花色复色分类方案，可为芍药属花色改良与新品种DUS测试提供参考。

Abstract:

Tree peony (Paeonia Sect. Moutan) is a traditional famous flower with a long history of cultivation in China. There are various cultivars of tree peony, which have rich variations in colors and shapes of flower. Itoh hybrid peony (P. Itoh Group) is the intersectional hybrid group crossed by tree peony group (P. Sect. Moutan) and herb peony group (P. Sect. Paeonia) of Paeonia. Multicolor is a special flower color pattern, both tree peony and Itoh hybrid peony are abundant in multicolor cultivars, but the existing floral classification cannot fully describe the floral characteristics of compound color varieties. Based on field investigation and literature analysis, this study classified the flower color of multicolor cultivars of tree peony and Itoh hybrid peony groups into 3 categories, including single plant multicolor, single flower multicolor and multicolored in florescence time, of which single flower multicolor was classified into 6 types. The results indicate that tree peony cultivars are rich in multicolor types, especially there are many multicolor cultivars in Northwest tree peony cultivar group. Itoh hybrid peony has a high proportion of multicolor cultivars, mainly of the gradient color type, and a few cultivars combine multiple types of stripes, spots, and single flower multicolor, etc. In this paper, we propose a new scheme for the classification of multicolor flower of both tree peony and Itoh hybrid peony which can be used as a reference for flower color improvement and DUS test of Paeonia.

Key words: tree peony, Itoh hybrid peony, multicolor cultivars, flower color type
