摘要:

针对云南玉米区域试验中基因型与环境(G×E)互作难以量化、试点冗余等问题,以2024年云南玉米联合体区试Ⅱ组数据为基础,整合方差分析与GGE双标图等方法构建协同评估体系,旨在优化试验试点布局并精准筛选适应当地立体气候条件的优良品种。结果表明,宣威、新平、沾益为核心固定试点,能够有效识别品种间的差异;广南、蒙自试点转型为适应特定环境(耐涝和耐高温高湿)的专项测试点;剔除昭通和祥云等冗余试点,试验成本降低30%,且仍能覆盖云南80%以上的玉米主产区。‘地沃20号’‘水金玉511’‘利民2号’在产量和稳定性方面表现突出,显示出优异的丰产稳产性,可为云南玉米产业的品种更新提供可靠选择。本研究提出的协同评估体系与试点优化方案,可为解决当前玉米品种繁杂、审定效率不高的问题提供科学支撑,有助于推动云南玉米种业的高质量发展。

Abstract:

To solve the problems of difficult quantification of genotype-environment (G×E) interaction and pilot redundancy in Yunnan maize regional trials, this study constructed a collaborative evaluation system based on the data of the regional trial group II of Yunnan maize consortium in 2024, integrating variance analysis and GGE biplot, aiming to optimize the layout of the trial pilot and accurately screen the excellent varieties adapted to the local complex vertical climatic conditions. The results indicated that Xuanwei, Xinping, and Zhanyi should be retained as core fixed sites, while Guangnan and Mengzi should be transformed into specialized testing sites. After removing the redundancy pilots of Zhaotong and Xiangyun, the trial cost was reduced by 30%, while still covering more than 80% of the main maize producing areas in Yunnan. In addition, three cultivars (‘Diwo 20’, ‘Shuijinyu 511’ and ‘Limin 2’) showed outstanding performance in both high yield potential and yield stability, which provided a reliable choice for variety renewal in Yunnan maize industry. Overall, the collaborative evaluation system and pilot optimization scheme proposed in this study can provide scientific support for solving the problems of complicated maize varieties and low approval efficiency, and help promote the high-quality development of Yunnan maize seed industry.
