Abstract: To comprehensively evaluate the rooting ability of different types and varieties of rose, and select the varieties with a strong rooting ability to provide reference for the future production and breeding of rose varieties, 59 rose varieties introduced and cultivated in Kunming, Yunnan Province, China were used as experimental materials, the root morphological indexes of rose cuttings were measured by WinRHIZO root analysis system, and the rooting ability of each rose variety was comprehensively quantitatively evaluated by principal component analysis and membership function analysis. The distribution of the root indexes of rose cuttings basically conformed to the normal distribution, except for the number of branches, the difference of the root indexes was small. Principal component analysis transformed 7 single indicators into 2 independent factors, with a cumulative contribution rate of 89.53%. Through membership function analysis, it was found that there were 23 varieties with a comprehensive score ≥0.40, accounting for 38.98%. In this study, 10 rose varieties with the strongest rooting ability were selected, including ‘Angela’, ‘Rouge Royal’, ‘Red Apple rose’, ‘Clg White Eden Rose’, ‘Highgrove’, ‘Pink Flamingo’, ‘Fensemenghuan’, ‘New Imagine’, ‘Billet Doux’ and ‘Crown Princess Margareta’, which can be used as a breed for large-scale production and as a parent for genetic improvement.

摘要: 以引种栽培于昆明地区的59个不同类型的月季品种为材料,利用WinRHIZO根系分析系统测量月季扦插苗的根系形态指标,利用主成分分析法、隶属函数法对各品种的生根能力进行综合量化评价,筛选生根能力较强的品种。结果表明,月季扦插苗各根系指标的分布情况基本符合正态分布,除分支数外,月季各根系指标的差异较小。主成分分析将7个单项指标转换成2个相互独立的因子,累积贡献率为89.53%。通过隶属函数分析发现综合得分值≥0.40的月季品种有23个,占38.98%。筛选出‘安吉拉’‘皇家胭脂’‘红苹果’‘白色龙沙宝石’‘海格瑞’‘火烈鸟’‘粉色梦幻’‘新想象’‘情书’和‘玛格丽特王妃’等10个生根能力较强的品种,可作为规模化生产的品种和遗传改良的亲本。
