河西走廊地区不同玉米杂交种材料的性状分析及综合评价
Trait Analysis and Comprehensive Evaluation of Different Maize Hybrids in the Hexi Corridor
摘要
Abstract
By analyzing the traits of maize hybrids in the Hexi Corridor region,this study aims to enhance the accuracy of innovative utilization of maize germplasm resources,scientifically match parental lines,and thereby improve the efficiency of elite variety breeding.20 maize hybrids were comprehensively analyzed for disease resistance,yield,and yield-related traits using methods including cluster analysis,grey relational analysis,and membership function evaluation.Results showed that stem rot was the primary disease affecting maize hybrids in the Hexi Corridor,with natural incidence rates ranging from 0%to 90.0%,and the highest incidence observed in the hybrid Er9706-121×Xian38.The contribution of yield-related traits to maize yield,in descending order,was ear diameter,hundred-kernel weight,number of kernel rows per ear,kernel setting rate,number of kernels per row,barren tip length,and lodging rate.Cluster analysis categorized the 20 hybrids into 3 groups.Group I included 11 medium-yield hybrids such as 3358×P74,1256×1CPSBC,1256×17PS,Demeiya3(the main control variety),3358×J216,3358×JiuBGB35,Xian38×J4CV3,3358×J4CV2BC,Jiu714×723,658BC0×723,and Er9706-121×723.Group II included 8 low-yield hybrids such as 91M9×Xian38,Er9706-121×Xian38,Er9706-121×F20,Huaqing105♀×3358,XD6CR×Er9706-121,J765×723,3358×1CPSBC3,and J765×Jiu714.Group III included only Heyu187(the second control variety),characterized as high-yielding.The membership function was used for comprehensive evaluation of maize yield and key traits.The D-values of the hybrids ranged from 0.265 to 0.693,with Heyu187(the second control variety),3358×J4CV2BC,658BC0×723,and Jiu714×723 exhibiting higher D-values and overall superior performance,indicating potential for further breeding trials.关键词
