【摘要】 小麦新品种推广和应用的重要参考指标包括其丰产性、稳产性和适应性。利用R语言的GGE双标图法分析新麦58在2021—2022年度生产试验(黄淮南部麦区)的产量数据,同时结合方差分析、变异系数、高稳系数、适应度和离优度等方法综合分析其连续三年的审定试验结果,以便提高对适应性、丰产稳产性及试点区分力评价的可靠性。结果表明,新麦58在陕西省宝鸡市、河南省郑州市和辉县表现出最强的适应性,其丰产稳产性综合排序第4,优于对照品种周麦18;河南原阳和江苏徐州是代表性和鉴别力均较强的试验地点;2019—2021年度新麦58较对照品种周麦18分别增产3.26%、3.84%和5.69%,差异极显著,其丰产性较好;高稳系数分别为86.3%、85.8%和87.9%,均高于对照品种周麦18,具有良好的稳产性;适应度和离优度分析结果说明不同试点条件下新麦58的适应性较强。更多还原

【Abstract】 Important reference indicators for the promotion and application of new wheat(Triticum aestivum L.) varieties include their high yield,stable yield and adaptability.The GGE dual-map method using R language was used to analyze the yield data of Xinmai58 in the 2021-2022 production trial(in the southern wheat-growing area of the Huanghuai region).Meanwhile,methods such as analysis of variance,coefficient of variation,high stability coefficient,fitness,and superiority were combined to comprehensively analyze the results of its consecutive three-year approved trials,in order to enhance the reliability of the evaluation of adaptability,high-yield and stable production,and the division force of the pilot area.The results showed that Xinmai58 demonstrated the strongest adaptability in Baoji City,Shaanxi Province,Zhengzhou City and Huixian City,Henan Province.Its comprehensive ranking of high and stable yield was 4th,which was superior to the control variety Zhoumai18.Yuanyang in Henan Province and Xuzhou in Jiangsu Province were experimental sites with strong representativeness and discrimination.From 2019 to 2021,the yield of Xinmai58 increased by 3.26%,3.84% and5.69% respectively compared with the control variety Zhoumai18,with extremely significant differences.Its high-yield performance was relatively good.The high stability coefficients were 86.3 %,85.8% and 87.9% respectively,all higher than the control variety Zhoumai18,demonstrating good stable production performance.The results of fitness and superiority analysis indicated that Xinmai58had strong adaptability under different pilot conditions.更多还原
