| 中文摘要: |
| 郑玉811（豫审玉20230007）是由郑州市农业科技研究院利用自选系郑7263和郑7241组配而成的杂交种。该品种抗病性突出，高抗或抗茎腐病、瘤黑粉病、小斑病、穗腐病、南方锈病；通过方差分析、产量对比、变异系数、高稳系数等对郑玉811的适应性、丰产性和稳产性进行分析，结果显示：在河南省玉米区域试验中，郑玉811增产点率高，较对照品种郑单958增产达到显著、极显著水平，变异系数小，高稳系数值高，说明郑玉811是一个适应性广、丰产性好、稳定性突出的玉米品种，适合在河南省进行推广种植。 |
| 英文摘要: |
| The new maize hybrid ‘Zhengyu 811’ was bred using the inbred line Zheng 7263 as the female parent and Zheng 7241 as the male parent by the Zhengzhou Academy of Agricultural Science and Technology. It was approved by the Henan Crop Variety Approval Committee in 2023, with the approval number Yushenyu 20230007. ‘Zhengyu 811’ exhibited outstanding disease resistance. According to disease resistance identification of crop varieties, ‘Zhengyu 811’ was highly resistant or resistant to Fusarium stem rot, Ustilago maydis, small spot disease, Fusarium ear rot, and southern corn rust. In this study, the adaptability, high yield, and yield stability of ‘Zhengyu 811’ were analyzed using variance analysis, yield comparison, coefficient of variation, and high stability coefficient. The results showed that in the regional maize trials conducted in Henan Province,‘Zhengyu 811’ exhibited a high yield increase rate, reaching significant and highly significant levels compared with the check variety ‘Zhengdan 958’ . It had a small coefficient of variation and a high value of the high stability coefficient, indicating that ‘Zhengyu’ 811 was a maize variety with wide adaptability, high yield, and excellent stability. It is therefore suitable for popularization and cultivation in Henan Province. |
