摘要: 调查了196 个中原牡丹品种的形态与观赏性状,针对园林绿化、盆花与切花生产3 种专用目标,采用灰色系 统理论,通过与标准品种关联度分析,进行品种评价与筛选。结果表明:针对园林绿化,适宜选择与标准品种关联 度逸0郾7 的品种;而对盆花与切花栽培而言,与标准品种关联度逸0郾8 的品种较为适合。据此筛选出45 个品种(约 占总数的1/4)推荐在生产中应用,包括42 个绿化品种、20 个盆栽品种、12 个切花品种。推荐品种中有7 个可同时 满足绿化、盆栽和切花生产的要求,应在生产中优先推广;有15 个品种在适合绿化应用的同时,也可用于盆花或切 花栽培;有3 个与20 个品种分别适合盆栽与绿化的单一应用目标。其余151 个品种(约占总品种数3/4)的评价结 果不理想,不提倡大规模用于生产。Abstract: Based on the investigation on morphological and ornamental characteristics of 196 cultivars in Paeonia ⅹsuffruticosa Zhongyuan Group, an analysis on the correlation degree with the standard cultivar (SC) by grey system theory was carried out to evaluate and select cultivars for three different specialized purposes, landscaping, potted-plant and cut-flower production. The results showed that, the cultivars had a correlation degree over 0.7 to SC can be selected to propagate for landscaping, and ones had a correlation degree over 0.8 to SC can be selected for potted-plants and cut-flower cultivation. According to the conclusion above, 45 cultivars out of 196 investigated ones were recommended for production application, including 42 for landscaping, 20 for potted-plants and 12 for cut-flowers. Among all the recommended ones, 7 cultivars had the priority in production because they can meet all the requirements of landscaping, potted-plant and cut-flower production simultaneously. Fifteen cultivars were suited for landscaping as well as for potted-plant or cut-flower production. Three and 20 cultivars were only suited for potted-plant and landscaping respectively. Only a quarter of the total cultivars were selected, and the rest 151 were not well suited for mass production due to their unsatisfactory evaluation results
