摘　　要：本研究旨在通过GGE双标图法(Genotype Main Effects and Genotype x Environment Interaction)探讨其对玉米新品种在高海拔地区黔西北的丰产性、稳产性和适应性的综合评价能力。研究选取了5个新的玉米组合,在7个不同试点进行了产量数据收集与分析。结果显示,这些试验点可以划分为2个主要的生态区。具体来说,盘州被识别为一个独立的生态区,而六盘水、赫章、大方、纳雍、水城和威宁则构成了另一个生态区。在所测试的玉米新组合中,‘惠农单5号’在高产和稳产方面的表现尤为突出。进一步的试验地点分辨力和代表性分析表明,盘州和大方这2个试验点的鉴别力强且具有较好的代表性。因此,本研究不仅为玉米新品种的综合评价提供了科学依据,还为未来试验地点的选择提供了重要的理论支持。The aims were to explore the main functions and characteristics of GGE double plot,and to select new maize varieties with high and stable yield.In this study,the yield data of 5 new maize combinations in 7 experimental sites were analyzed by GGE-biplot,the high yield,stable yield and adaptability of maize varieties tested at high altitudes in northwest Guizhou were evaluated,and the discrimination and representativeness of the test sites were analyzed.The results showed that the experimental sites could be divided into two ecological zones,with Panzhou as an ecological zone and Liupanshui,Hezhang,Dafang,Nayong,Shuicheng and Weining as an ecological zone.‘Huinongdan No.5’performed well in high and stable yield.The results showed that Panzhou and Dafang were the best experimental sites with high discrimination and good representativeness.This study provided a theoretical basis for comprehensive evaluation of new maize varieties and selection of experimental sites.
