以“玉盘珍”“玉瓣绣球”“夜光杯”等30个紫斑牡丹品种为试验材料,选取9个性状为评价因子,采用灰色关联度分析法,研究紫斑牡丹品种各性状指标对其品种总体表现的影响,综合评价品种优劣,以期筛选出适合洛阳地区生长且具有较好观赏性的紫斑牡丹品种,探索科学的牡丹品种综合评价体系,为牡丹育种和品种推广提供参考。结果表明:参试的30个紫斑牡丹品种中有20个品种与参考品种的加权关联度较大(r>0.618 6),具有良好的适应性和观赏性。其中,“紫海银波”与参考品种的加权关联度最大(r=0.812 2),综合性状最优;其次是“绣球红”(r=0.748 8)和“夜光杯”(r=0.729 6),综合性状优良;而“淡容装”关联度最小(r=0.531 7),综合性状最差。评价结果与品种的实际表现比较一致,说明利用灰色关联度分析法对紫斑牡丹进行性状综合评价是科学可行的。
Thirteen varieties of purple peony, such as “Yu panzhen”, “Jade petal Hydrangea” and “Luminous Cup”, were selected as the experimental materials. Nine traits were selected as evaluation factors and gray relational grade analysis Comprehensive evaluation of the merits of the varieties, in order to screened the purple peony varieties suitable for growing in Luoyang region with good ornamental, to explore the scientific evaluation system of peony varieties for peony breeding and variety promotion for reference. The results showed that 20 of the 30 cultivars tested had a higher weighted correlation with reference cultivars (r> 0.618 6), which showed good adaptability and ornamentation. Among them, “Zihai Yinbo” had the highest degree of weighted correlation with reference cultivars (r = 0.812 2), with the best comprehensive characters; followed by “Hydrangea red” (r = 0.748 8) and " (r = 0.729 6). The comprehensive characters were excellent, while the lightness tolerance was the least (r = 0.531 7). The comprehensive characters were the worst. The results of the evaluation are in good agreement with the actual performance of the cultivars, which shows that it is scientifically feasible to evaluate the traits of purple peony through the gray relational analysis.
