甜菜品种主要性状间相互影响关系的分析

Analysis of the interaction between the main characters of Sugarbeet Varieties

本研究以内蒙古农业大学职业技术学院园区2019年栽培的22个甜菜品种为材料,研究了甜菜的主要性状及其差异,并以9项指标为依据对这些品种进行综合评价。采用主成分分析(PCA)和聚类分析(CA)对甜菜性状的变异性进行评价,并对各变量的贡献进行排序。根据PCA法将22个甜菜品种的品质指标分为4个主成分,累积方差贡献率为79.748%,反映了所考察性状绝大部分信息,以及各公因子中有关性状的相关程度。根据CA法将甜菜品种重新分为6类。结果表明,第一类、第二类、第三类品种品质较好。将这两种方法结合起来,探讨了各类品种栽培管理措施和改良目标。

In this study, 22 sugarbeet varieties cultivated in 2019 in Inner Mongolia Agricultural University Vocational and Technical College were used as materials to study the main characters and differences of sugarbeet, and the comprehensive evaluation of these varieties was carried out based on 9 indexes. The main component analysis(PCA) and cluster analysis(CA) were used to evaluate the variability of sugarbeet characters, and their contribution to each variable sort. According to the PCA method, the quality indexes of 22 sugarbeet varieties were divided into four main components, and the cumulative variance contribution rate was 79.748%, which reflected most of the information of the investigated characters and the correlation degree of the related characters in each common factor. Sugarbeet varieties were divided into 6 groups according to CA method. The results showed that the first, second and third varieties had better quality. In this paper, the two methods are combined to discuss the cultivation and management measures and improvement objectives of various varieties.
