本文应用模糊数学原理,对我国向日葵食用种多因子样本集进行了聚类分析。在聚类分析的基础上,将我国向日葵食用种为几个地区间的差异,指出了多因子综合指标下的品种间的亲疏关系。这为我国向日葵食用种杂交亲本选配提供一定的参考。
In this paper, the principle of fuzzy mathematics is used to cluster the multi-factor sample set of sunflower edible species in our country. On the basis of cluster analysis, the edible species of sunflower in our country is the difference between several regions, and the relationship between varieties is indicated under the multi-factor comprehensive index. This provides a reference for matching parents of sunflower edible hybrids in our country.
