方差分析和灰色关联分析在玉米品种评价中的应用
Application of Analysis of Variance and Grey Correlation Analysis in Maize Variety Evaluation
摘要
Abstract
In order to select suitable methods for maize variety evaluation,analysis of variance(ANOVA)and grey correlation analysis were employed to analyze and compare ear traits and yields of various maize varieties at three screening test sites in 2020.The results of ANOVA showed that the yields of Dunyu 735,Yayu 988,Zhongyu 335,Huayu 11,Xianyu 696 and Xikang 18 were extremely significantly higher than that of the control variety Liangdan 4.The results of grey correlation analysis indicated that ear diameter had the greatest effect on the yields of various varieties;Dunyu 735,Zhongyu 335,Zhongyu 2 and Yayu 988 exhibited higher correlation and good comprehensive traits.This suggests that different evaluation methods can lead to different evaluation and selection results for maize varieties.ANOVA can be adopted for evaluation in multiple environments and only yield traits involved,while grey correlation analysis can be used for evaluation in a single environment and multiple trait indicators involved.关键词
