对4个类型的月季(茶香月季、丰花月季、藤本月季和微型月季),共计238个品种的植株性状、花部性状和抗性等27个性状进行详细观测,结合月季在北京园林绿化中的应用形式,利用主成分分析方法,筛选出了13个性状指标。以准确筛选适合北京地区栽植的新优月季品种为目标,基于植株性状、花部性状、和抗性3个层面,利用层次分析法,分别构建了针对四大类群月季的综合评价体系。应用该评价体系,筛选出综合性状优秀的杂交茶香月季品种20个、丰花月季品种11个、藤本月季品种3个、微型月季品种8个。为今后合理筛选适宜北京地区栽植的月季品种提供了一条有效的途径。 |

Abstract: |
The 27 biological characteristics of 238 rose cultivars of 4 types of roses, including plant traits, floral traits and resistance, were investigated and analyzed in this study. The 238 rose cultivars consisted of 187 Hybrid Tea Roses, 26 Floribunda Roses, 13 Climber Roses and 16 Miniature Roses. Based on the application of roses in Beijing landscaping, by using the method of principal component analysis, 13 indicators were selected from the 27 characteristics. To select new rose cultivars suitable for planting in Beijing, by using the analytic hierarchy process, based on plant traits, floral traits and resistance, a comprehensive evaluation system was constructed for the 4 groups of roses?respectively. By using this evaluation system, from the 238 cultivars, some excellent rose cultivars were selected, including 20 Hybrid Tea Roses, 11 Floribunda Roses, 3 Climber Roses, and 8 Miniature Roses. This paper provides an effective method for the selection of excellent rose cultivars suitable for planting in Beijing. |
