Study on the Relationship of Maize Varieties Based on Clustering and Stepwise Regression Analysis
摘要
Abstract
The 15 characters of 41 maize varieties are earned in comparison experiment.The relationship of maize varieties was studied based on clustering and stepwise regression analysis.The results showed that maize varieties were clustered into five types.Class Ⅲ and Ⅳ showed high yield,class Ⅰ,II and Ⅳ showed strong resistance to lodging,class V shows strong resistant to disease."Optimal"regression equation was established between yield and other characters.The effect of the Characters of ear diameter,hundred grain weight,empty stem rate and plant height on maize yield are significant,and their effects reduced progressively.关键词
