中国芍药品种资源表型性状多样性分析
Diversity Analysis of Phenotypic Traits for Chinese Herbaceous Peony Cultivar Resources
摘要
Abstract
Genetic variation analysis,correlation analysis,cluster analysis and principal component analysis were used to analyze the diversity of 48 phenotypic traits in 167 Chinese herbaceous peony cultivars.The results showed that both qualitative and quantitative traits of Chinese herbaceous peony cultivar resources had high levels of phenotypic diversity,with quantitative traits being more diverse than qualitative traits.Traits such as compound leaf type,flower color,stamen petal shape and color,gynoecium stigma color,scale bud differentiation ability,and flower branch length are important reference indices for measuring the level of phenotypic diversity in herbaceous peony cultivars.R-type cluster analysis classified quantitative traits into 4 categories,mainly reflecting growth potential and leaf traits,floral traits,flowering cycle traits,and phenological period traits.Q-type cluster analysis classified the herbaceous peony cultivar resources into 3 groups,and the number of cultivars in group Ⅰ accounted for 37.13％,which mainly showed late phenological period.The number of cultivars in group Ⅱ accounted for 32.93％,which mainly showed strong growth potential and large flower diameter,The number of cultivars in group Ⅲ accounted for 29.94％,which was mainly characterized by strong scale bud differentiation ability and large number of flowers.All the quantitative traits,except for the single flowering period,differed to varying degrees among the groups of cultivar resources.Principal component analysis allowed the generalization of the traits with the highest contribution to phenotypic variation into phenological period factor,leaf factor,flowering period factor,flower factor,and growth factor.关键词
