摘要:
目的 筛选出适宜江苏扬州地区种植的国外芍药资源,建立引种国外芍药品种综合性评价体系,从而能更好地为扬州乃至长江中下游地区芍药种质资源创新及产业化发展提供支撑。 方法 对引种的21个国外芍药品种适应性、植株特性和观赏性进行观测,共选取12个性状指标,并采用层次分析法(AHP)进行综合评价,最终得出每个品种的综合性状评分值并进行排名和等级划分。 结果 确定了12个评价指标的权重值,其中热害指数、花姿态、鳞芽分生能力和单朵花期所占比重较大,分别为0.4180、0.1496、0.1393、0.0898。依据品种综合性评价得分,将评分结果划分为3个等级,皮特布兰德等8个品种综合评分大于3.5,位列I级,适宜在扬州地区推广应用;七叶树之恋等6个品种综合评分为3.0~3.5,位列II级,具有一定的应用价值,可适量推广;花季少年等7个品种综合评分小于3.0,位列III级,不推荐在扬州地区引种栽培和推广应用。 结论 应用层次分析法建立的综合评价体系能够准确地对国外芍药资源进行评价与分级。 Abstract:Objective In order to screen out foreign peony resources suitable for planting in Yangzhou, Jiangsu, and establish a comprehensive evaluation system for introducing foreign peony varieties, it can better provide support for the innovation and industrialization development of peony germplasm resources in Yangzhou and even the middle and lower reaches of the Yangtze River. Method The adaptability, plant characteristics, and ornamental quality of 21 introduced foreign paeonia varieties were observed. A total of 12 personality indicators were selected and comprehensively evaluated using the analytic hierarchy process (AHP). Finally, the comprehensive character score of each variety was obtained and ranked and graded. Result The weight values of 12 evaluation indicators were determined, among which the heat damage index, flower posture, bud differentiation ability, and single flower stage accounted for a large proportion, respectively 0.4180, 0.1496, 0.1393, and 0.0898. According to the comprehensive evaluation score of varieties, the scoring results are divided into three grades. The comprehensive score of 8 varieties such as' Peter Brand 'is greater than 3.5, ranking Level I, suitable for promotion and application in Yangzhou region; The comprehensive score of 6 varieties such as' Buckeye belle ' is between 3.0 and 3.5, [1] ranking Level II, which has certain application value and can be appropriately promoted; The comprehensive score of 7 varieties such as' Teenage Boy 'is less than 3.0, ranking Level III, and it is not recommended for introduction, cultivation, and promotion in Yangzhou.Conclusion The comprehensive evaluation system established by using the analytic hierarchy process can accurately evaluate and grade foreign paeonia resources. -
