Preliminary Comparison of Several Statistical Models for Sugarcane Variety Stability Analysis

Several statistical analysis models for estimating the sugarcane variety stability were compared in this paper using the data of sugarcane varietal regional trial in Guangdong province in 2009.The results showed that Finlay and Wilkinson regression model was easier,but both the analysis of the other two models were more comprehensive,and there was a bit difference between AMMI model and LR-PCA model.In practice,while the proper statistical method was usually considered according to the different data,it should be also considered that the same data be analyzed with different statistical methods in order to get a more reasonable result by comparison.
