摘　　要：作物品种产量和稳产性是区域试验评价的重要任务,不同品种的产量、适应性受品种基因型、环境及其交互作用影响。应用GGE双标图方法分析2017~2018年广东省甜玉米区域试验19个参试品种在7个试点的产量数据。结果表明,金百甜15在丰产性和稳产性方面综合表现最好,其适应性也最强,综合品质比对照优势明显;其次是品种HMT9、JBT28和MYT009。GGE-plot方法能够直观有效地评价品种的适应性、丰产性和稳定性。Yield and stability of crop varieties are the important tasks in the evaluation of regional trials.The yield and adaptability of different varieties were influenced by genotype,environment,and their interactions.In this study,the yield data of 19 varieties(control included)in 7 test sites of Guangdong province sweet corn regional trials during 2017-2018 were analyzed by GGE-biplot.The results showed that Jinbaitian 15 had the best overall perfor⁃mance in terms of yield and stability,its adaptability was also the strongest,and its overall quality had obvious ad⁃vantages over the control,followed by varieties HMT9,JBT28 and MYT009.The research also showed that GGE-bi⁃plot method can visually and effectively evaluate the adaptability,fertility and stability of varieties.
