| 中文摘要: |
| ：2013 年1 月至2015 年2 月，对生产应用上的12 个蝴蝶兰品种进行观察统计，应用变异分析和主成
分分析建立评价体系。结果表明：15 个性状的平均变异系数为0.3428，侧分枝数的变异系数最大、为1.8747，叶宽
的变异系数最小、仅0.1175，各指标变量之间相互独立又密切联系；采用主成分分析法对12 个蝴蝶兰的15 个主
要性状进行分析，前5 个主成分累积贡献率达89.64%，包含了15 个性状的绝大部分信息，通过计算各品种的综
合得分值及其组培、栽培特性，得出第1 类、第2 类和第4 类共8 个优良品种值得进一步开发利用。 |

| Twelve varieties of Phalaenopsis applied in production were observed and counted from January 2013 to
February 2015. A synthetic assessment system was established by means of variation analysis and principal component
analysis. The results showed that the average coefficient of variation of 15 traits was 0.3428， the coefficient of variation of
lateral branching number was the largest with 1.8747，and the coefficient of variation of leaf width was the smallest with
0.1175. The processing evaluation variables were relatively independent but closely related. The main traits of 12 varieties
were analyzed by principal component analysis. The cumulative contribution rate of the first five principal components
reached more than 85%，which contained the most information of 15 traits，total 8 varieties in the first，second and fourth
category were worth further development and utilization according to the calculation of comprehensive score and the
features of tissue culture and cultivation |
