摘要
Abstract
To further diversify maize variety resources in Longnan City and facilitate a substantial increase in per-unit-area yield,field trials were conducted to evaluate 19 new national approved maize varieties based on agronomic traits,ear traits,stress resistance,yield performance,and quality traits at Huicheng Basin,Longnan City,in 2024,with the objective of identifying new maize varieties suitable for promotion in this region.Results showed that among the tested varieties,Cunli 88 and Zhongxiayu 6 exhibited yield increases of 12.2%and 2.2%,respectively compared with the control variety Xianyu 335,while the other varieties showed yield decreases ranging from 2.5%to 38.4%.Zhongxiayu 6 demonstrated both excellent yield potential and stress resistance,making it suitable for cultivation in the Huicheng Basin of Longnan City and regions with similar climatic conditions.Although Cunli 88 showed good yield performance,its poor disease resistance and relatively high lodging rate posed risks for large-scale promotion in Longnan,Gansu.Further evaluation is required for other varieties before regional adoption.关键词
