蝴蝶兰70份资源观赏性状综合评价

本研究对70份蝴蝶兰资源在开花时期进行株幅、叶长、叶宽、花梗长、花梗粗、花朵长度、花朵宽度、单株花朵数、花色、双梗率、分叉数和花序梗长度等品质性状进行测量调查,在R型聚类分析和Q型聚类分析对蝴蝶兰进行分类研究的基础上,采用变异系数分析、层次分析法和方差分析法进行综合评价。结果表明：蝴蝶兰品种间差异性最显著的是分叉数,变异性最大的也是分叉数;花朵长度、花朵宽度、花色、叶宽、单株花朵数、花梗粗、叶长和花序梗长度性状相似度高;其余各个性状间相似度相差较远,表明蝴蝶兰表型性状独自进化。通过以上研究全面客观的对70份蝴蝶兰资源进行综合评价,为新品种选育做出贡献。

Comprehensive Evaluation of 70 Ornamental Characters of Phalaenopsis

The leaf length,leaf width,peduncle length,pedicel thick,length,width,number per plant flowers,flower,flower color,double rate,branch number,and peduncle length measure quality traits of 70 butterfly orchid resources in the flowering period were investigated.Based on R type cluster analysis and Q type cluster analysis,the species were comprehensively evaluated with coefficient of variation analysis,analytic hierarchy process and variance analysis methods.The results showed that the most significant difference between the species was the number of bifurcation,and the largest variability was the number of bifurcation.The similarity of flower length,flower width,color,leaf width,number of flowers per plant,peduncle width,leaf length and peduncle length was high.The similarity of the other traits was far from each other,indicating that the phenotypic traits of phalaenopsis evolved independently.Through the above research,the comprehensive evaluation of the 70 species was conducted comprehensively and objectively,contributing to the breeding of new varieties.
