月季品种资源的分类与评价

以引进的13个月季品种资源为试材,采用方差分析和系统聚类法对其进行了分类与评价.结果表明:13个月季品种在花色、叶片大小等性状上存在显著差异,反映出所调查资源丰富的遗传多样性;基于8个数量性状的聚类分析,在遗传距离2.91处,将13月季个品种分为4组,其中1号品种单独为一组,5,13,6号品种聚为一组,3,7,12号品种聚为一组.2,8,9,10,11,4号品种为一组.1号月季品种蔓生、低矮,花小,花繁密,是良好的地被资源;5,6,13号株高较高,花大,枝条数目中等,是良好的切花品种资源;其余品种可用于道路美化或花坛应用.

Evaluation and classification of the Rosa chinensis cultivars

13 rose varieties,based on their 10 ornamental characters,were classified and evaluated by variance and cluster analysis.Results showed that 13 rose cultivars had significant differences in many characters such as flower color,leaf size,et al,which reflected the rich genetic diversity of these resources.Based on 8 quantitative characters,13 varieties could be divided into 4 groups at the genetic distance 2.91,in which No.1 was seperated into a group,No.5,No.13 and No.6 were clustered another group,No.3,No.7...
