10个麦后夏播玉米品种在阿克苏地区农艺性状、产量性状和品质性状的分析OA

[Objective]This study aimed to screen summer-sown maize varieties suitable for the"winter wheat-summer maize"double-crop-ping system in the plain areas of the Aksu Region,thereby providing a scientific basis for rational variety distribution and the promotion of this double-cropping system.[Method]Ten summer-sown maize varieties were used as test materials.Their agronomic traits,yield-related traits,and quality traits were investigated,and a grey relational analysis was employed to comprehensively evaluate the performance of the varieties.[Result]Significant differences were detected among the traits of the tested varieties.Plant height,ear length,number of leaves,number of rows per ear,and number of grains per ear showed significant or highly significant positive correlations with yield.Quality traits such as starch content and protein content exhibited weak correlations with plant traits and yield-related traits.Zhongyu 303 exhibited the optimal yield traits and superior agronomic traits;Xinyu 42 showed excellent lodging resistance and superior grain quality;Xinyu 101 had the highest starch con-tent;while Xianrui 921 displayed overall poor performance.[Conclusion]Zhongyu 303,Xinyu 42,and Xinyu 101 performed well,whereas Xinyu 61 and Xianrui 921 performed poorly.For Zhongyu 303,it is recommended to pair it with early-maturing wheat varieties and implement timely early sowing.
