摘　　要：解析黄淮区试各试验点油菜主要农艺性状的基因与环境互作关系,并对各试验点进行评价。本研究用GGE双标图方法对2010—2015年油菜黄淮区试农艺性状数据进行分析,用油菜产量三因素的基因与环境互作结果对试验点进行分类,并按照区分能力和代表性对各试验点进行评价。结果显示,富平试点的产量、单株角果数、株高和分枝部位表现最好。淮安试点的千粒重、单株产量、分枝数和主花序角果数表现最好,成县试点的每果粒数和主花序结角密度表现最好。按单株角果数和千粒重分析,宿州试点都单独聚为1类;杨凌试点的区分能力和代表性最高。宿州试点被划分为另外一个品种生态区,杨凌试点是最理想的试验点。To analyze the interaction relationship between the genes of main agronomic characters of rape and the environment in Huanghuai Regional Trial Sites, and to evaluate all the trial sites, GGE biplot method was used to analyze the agronomic characters of rape in the National Huanghuai Regional Trials from 2010 to 2015.Trial sites were clustered based on the interaction results between the genes of three yield components and environment, and they were evaluated according to the discriminating ability and representativeness. Theresults showed that the yield, pods per plant, plant height and effective branch height at Fuping Site were thebest. 1000-seed weight, yield per plant, primary branches and pods of main raceme at Huaian Site were thebest. Seeds per pod and pods density of main raceme at Chenxian Site were the best. Based on both of pods perplant and 1000-seed weight, Suzhou Site was clustered into one group; and the discriminating ability andrepresentativeness of Yangling Site were the highest. Suzhou Site was classified into another variety eco-region. Yangling Site was the most ideal site in Huanghuai Region.
