摘　　要：【目的】评价河南主要荷花品种资源观赏性,为河南观赏荷花的栽培和育种提供参考。【方法】根据灰色系统理论中的灰色局势决策原理,利用性状加权局势决策方法对127个河南主要栽培荷花品种(系)的立叶长、立叶宽、叶柄高、群体花期等15个主要观赏性状进行赋值、无量纲化处理、关联分析,构建综合评价模型,根据此模型对127个品种(系)进行综合排序。【结果】构建的河南荷花综合观赏性评价模型为Γij=0.05X1+0.05X2+0.04X3+0.12X4+0.12X5+0.02X6+0.02X7+0.08X8+0.12X9+0.12X10+0.06X11+0.06X12+0.05X13+0.05X14+0.04X15,根据此模型评价127个河南主要栽培荷花品种(品系),综合观赏性状排在前10位的依次为大洒锦、雪里红、傲霜、鄂莲4号、冬红、灵宝鼎湖湾品系、眼儿媚、息县陈棚汪湖品系、曙光和罗山高湾村品系。【结论】利用灰色理论系统分析法构建的评价模型可用于评价河南主要荷花品种资源的观赏性。[ Objective ] Ornamental evaluation of main lotus cultivars resources in Henan was conducted to provide references for lotus cultivation and breeding in Henan. [Method ]According to the grey situation decision-making principle of grey system theory, the main characters （length of ripe leaves, width of ripe leaves, height of leaf petiole, flowering phase of group ） of 127 lotus cuhivars （strains） were analyzed using the method of character weighting. A comprehensive evaluation model was built through assignment, dimensionless and relational analysis of the 15 main ornamental characters. The 127 lotus euhivars （strains） were sequenced using this model. [Resuh]Henan lotus comprehensive evaluation model was Гij=0.05X1＋0.05X2＋0.04X3＋0.12X4＋0.12Xs＋0.02X6＋0.02XT＋0.08Xs＋0.12X9＋0.12XI0＋0.06X11＋0.06XI2＋0.05XI3＋0.05X14＋ 0.04X15, based on which the top ten cultivars of 127 lotus cultivars （strains） on general ornamental characters were Dasajin, Xuelihong, Aoshuang, Eliansihao, Donghong, Lingbao Dinghu bay lotus strains, Yanermei, Xixian Chenpeng Wang lake lotus strains, Shuguang and Luoshan Gaowan village lotus strains. [Conclusion]Using grey system theory, a model of lotus cultivars sources is established for ornamental evaluation in Henan.
