[目的]比较研究用以评价甘蔗品种稳定性的三种模型。[方法]以广东省2009年甘蔗品种区域试验产量数据为例,对线性回归模型、AMMI模型和LRPCA模型在评价甘蔗品种稳定性方面的应用进行了比较。[结果]回归法计算简便、直观,AMMI模型和LRPCA模型的分析结果则更全面、深入,而这两种模型之间仍存在着一定差异。[结论]实际操作中,在根据不同的数据资料选择相适宜的分析方法的同时,也可以采用不同的方法进行分析,通过比较选择较为合理的结果。 [Objective] Three models for evaluating the stability of sugarcane varieties were comparatively studied. [Method] With the data of regional experiment of sugarcane variety in Guangdong in 2009 as an example, the application of linear regression model, AMMI model and LRPCA model in evaluating the stability of sugarcane varieties were compared. [Results] The regression method was simple and intuitive. The analysis results of AMMI model and LRPCA model were more comprehensive and in-depth. There were still some differences between the two models. [Conclusion] In practice, different methods can be used to analyze the data according to different data, and the more reasonable results can be obtained by comparison.
