74份丁香属种质资源表型多样性分析与综合评价
Phenotypic Diversity Analysis and Evaluation on 74 Syringa Germplasm Resources
摘要
Abstract
Using 74 germplasm resources of Syringa plants as the research object,24 phenotypic traits were selected for correlation analysis,principal component and Q-type clustering analysis,to clarify the diversity and variation characteristics of phenotypic traits in Syringa germplasm resources.The findings indicated that 74 ger-mplasm resources of Syringa plants exhibit rich phenotypic diversity,with a wide range of variations in flower color,corolla tube color,and leaf color traits;Correlation analysis shows that there are varying degrees of correla-tion between various quantitative traits,and most of them have significant or extremely significant positive correl-ations.Based on systematic clustering analysis,74 Syringa germplasm resources were divided into 3 major groups.The first category includes 7 species,characterized by large leaves,long petioles,large flower diameters,long inflorescences,and a high number of small flowers;The second category includes 28 species,characterized by small leaves and small flower diameter;The third category includes 39 species,which are mainly character-ized by multiple double petals and the least amount of small flowers;Principal component analysis shows that the cumulative contribution rate of the first 9 principal components reaches 81.27%.According to the comprehensive score of principal components,at the top of Syringa,such as Syringa vulgaris'Sensation'have the best com-prehensive performance.关键词
