Analysis of Kernel-Related Traits and Protein Content of Maize Inbred Lines
To evaluate the genetic variation of kernel-related traits and total protein content in maize inbred lines,excellent maize inbred lines were screened.The variation analysis,correlation analysis and cluster analysis of kernel-related traits and total protein content were carried out using 298 maize inbred lines.The results indicated that total protein content varied from 3.04％to 14.10％,with an average of 9.03％,the coefficient variation of total protein content and kernel-related traits ranged from 9.13％to 26.05％.Total protein content was significantly negatively correlated with total starch content,amylose content,kernel length and 100-kernel weight,and it was significantly positively correlated with total soluble sugar,crude fat and reducing sugar.There were significant differ-ences in total protein content and kernel length among different subgroups.The 298 maize inbred lines were divided into six groups by cluster analysis.Group Ⅳ containing 5 maize inbred lines(CIMBL156,CIMBL83,HSBN,S37 and CIMBL120)had better performance in total protein content and kernel-related traits.
