Correlation Studies on Root Lodging Resistance Traits in Maize Inbred Lines
摘要
Abstract
The purpose of the study investigated the correlation of maize inbred lines in jointing(V6)and milk ripening(R3).The ultimate tensile force,root weight,root length,stem diameter,root volume,root surface area,root projection area and root tip number were measured during the jointing period,aerial root number,aerial root diameter,aerial root length,secondary root diameter,secondary root length,68 maize inbred root length and stem thickness during the ripening period.The study shows that the ultimate tension of maize inbred line,root fresh weight,root diameter,root length,root volume,root surface area,projection area and root tip number were all positively correlated.The correlation coefficient was between 0.37 and 0.62,and the correlation coefficient of root ultimate tension and root fresh weight was the highest(0.58).The correlation coefficient of the ultimate tension value and other traits is between 0.02 and 0.45.The ultimate tension was positively correlated with the length of aerial roots,the number of secondary roots,subroot diameter and stalk thickness,and the correlation coefficient of the ultimate tensile value and the number of secondary roots was 0.45.There was a significant positive correlation between the lodging tension and the ripening stage.关键词
