摘要：

对滇牡丹(Paeonia delavayi)10个花色类群的13个数量性状和5个质量性状进行了调查及统计分析，结果表明：(1)未发现所有花部性状均为同色的花色类群；(2)从花色与其它质量性状的连锁看，绿色类群均具绿色柱头，且是唯一存在直立花朵、绿色花丝、绿色花药的类群；(3)10个花色类群13个数量性状的平均变异系数范围为32.80%～50.56%，说明不同类群内个体间的性状稳定性差异较大；(4)10个花色类群平均表型分化系数为42.25%，表明滇牡丹10个花色类群表型变异主要来源于类群内，类群间的表型变异也很突出；(5)据花色演化趋势，初步推断云南省迪庆州中甸、德钦一带可能为滇牡丹的起源中心。

Abstract:

Paeonia delavayi has great value in P.suffruticosa new variety breeding because of its profuse flower color. Ten different flower color groups of P.delavayi were investigated and studied，based on 13 quantitative characters and 5 qualitative characters. Morphological variation patterns and differentiation levels among different groups were revealed, providing data and evidence for cross breeding and systematics study. The results showed that: (1) there was no flower color group which all its flower components was in the same color; (2) Flowers of green color group had green stigma exclusively which might imply the linkage relationship between them. Furthermore，green color group was unique by its erect flowers，green filaments，and green anthers; (3) the average variation coefficient of 13 quantitative characters of 10 groups ranged from 32.80% to 50.56%，which indicated that the character stability of individual plants within group were quite different from each other; (4) the mean phenotypic differentiation coefficient of 10 groups was 42.25%，which indicated that the phenotypic differentiation was distinguished among different color groups; (5) it was suggested that P.delavayi should have been originated from the areas of Shangri-la and Deqin of Yunnan Province according to its evolutionary trend of flower color.
