玫瑰种质资源的综合评价与品种优选

Comprehensive Evaluation and Variety Selection of Rose Germplasm Resources

以引种保存的27个玫瑰品种为实验材料,结合玫瑰特性及实际生产,对其主要品种特性进行样本分析,通过咨询专家对玫瑰的观赏性、适应性及抗性、经济性状等3个方面15个指标进行调查,应用层次分析法(AHP)对其性状赋权,对27个玫瑰品种进行分析筛选,建立起玫瑰种质资源综合评价体系,并筛选出适宜推广的玫瑰栽培品种。结果表明,引种的27个玫瑰品种中大部分可适应贵州栽培,丰花玫瑰各方面性状表现优秀,苦水、亮叶、紫枝等11个品种表现优良,建立起的玫瑰评价体系能较全面地评价引种的玫瑰种质,因此玫瑰种质资源评价体系的建立对于玫瑰种质资源收集、新品种选育及栽培推广有重要的指导作用。

In this paper, the 27 rose varieties introduced and preserved were selected as experimental materials to analyze the mainly varietal characteristics of the varieties combined with the characteristics of rose and actual production. Synchronously, 15 indexes of roses in three aspects, such as ornamental ability, adaptability and resistance, and economic traits were also investigated by consulting experts, and Analytic Hierarchy Process(AHP) was used to give weight to its traits, and 27 rose varieties were analyzed and screened. Finally, a comprehensive evaluation system of rose germplasm resources was established based on the above research, and suitable rose varieties were further screened out. The results showed that most of the 27 introduced rose varieties could be adapted to cultivation in Guizhou. The rose variety Fenghua appeared excellent performance in all aspects, and 11 varieties including Kushui, Liangye and Zizhi had also excellent performance. And, the established rose evaluation system coulf comprehensively evaluate the introduced rose germplasms. Therefore, the evaluation system of rose germplasm resources played an important guiding role in the collection of rose germplasm resources, breeding of new varieties and promotion of cultivation.
