Abstract
This study aimed to select winter wheat varieties suitable for promotion in high-standard farmlands in Zhuanglang County,accelerate variety renewal,and provide a solid foundation for increasing local grain yield and ensuring food security.Using Longjian 120 as the control variety,the economic characters and resistance of 16 winter wheat varieties were compared and analyzed.The results showed that Xinong 158,12164-4-1-5,Lantian 58,Zhongliang 48,Taikemai 50,Yannong 1212,Zhuanglang 17,12437,and 13288 had yield increases of 27.84%,15.78%,14.85%,8.53%,5.10%,4.64%,4.18%,1.39%,and 1.16%,respectively,compared to the control variety Longjian 120,while the remaining varieties showed yield reductions.Among them,12164-4-1-5,Lantian 58,Zhongliang 48,Zhuanglang 17,and 12437 exhibited strong tillering ability,high kernel number per spike,high thousand-kernel weight,and moderate plant height.Which demonstrated good yield potentials,and resistance to lodging,drought,and cold,making them suitable for large-scale promotion in high-standard farmlands in Zhuanglang County.Xinong 158 showed excellect traits,high yield potential,strong lodging and cold resistance,and high resistance to powdery mildew,but was relatively susceptible to stripe rust,making it suitable for small-scale planting in combination with other varieties.关键词
