牡丹品种种质资源评估模型

Research on Assessing Model and Classifying of Luoyang Peony Variety Resources

以中国传统名花──洛阳牡丹330个品种为研究材料，采用模糊数学方法构造项目、类目反应表，建立专家打分系统．在此基础上构造评估模型，并对每个品种进行评估．采用方差分析及参数估计的方法将330个品种划分为4等:其中Ⅰ等（优)含16个品种，为大家共认的珍稀品种；Ⅱ等（良）含51个品种，为牡丹的上等品种；Ⅲ等（一般）含231个品种；Ⅳ等（差)含32个品种．本研究较科学地解决了洛阳牡丹品种种质资源的定量评估及等级划分问题，为牡丹品种的计算机管理、信息交流、选种育种、市场销售提供了定量依据．
