基于AMMI和GGE双标图的贵州不同生态区春玉米丰产性稳产性和试点辨别力评价

Evaluation of the High Yield,Stability and Pilot Discriminative Power of Spring Maize in Different Ecological Areas of Guizhou Based on AMMI and GGE-biplot

基于AMMI模型和GGE双标图对2018~2019年贵州春玉米11个品种、5个试点的产量数据进行丰产性和稳产性分析,评价试点的辨别力和代表性。结果表明,2018年中金玉838、新中玉801、先玉1171丰产性较好,靖单14、先玉1171和金玉838的稳产性较好;威宁、毕节试点的代表性较好,安顺、铜仁试点辨别力较强。2019年中金玉838、新中玉801、先玉1171丰产性较好,先玉1171和金玉838和兴玉3号的稳产性较好;安顺、兴仁试点的代表性较好,毕节、威宁辨别力较强。综合分析,金玉838的丰产性、稳产性均较强,综合表现最佳,威宁和毕节具有较高的试点辨别力和代表性。

Based on AMMI model and GGE double plot,this paper analyzed the yield data of 11 varieties and 5 pilot plants of spring maize in Guizhou in 2018-2019 for high yield and stable yield,and evaluated the discrimina⁃tion and representativeness of the pilot plants.The results showed that in 2018 Zhongjingyu838,Xinzhongyu801,Xiangyu1171 had better yields,Jingdan 14,Xiangyu1171 and Jingyu 838 had better stability;Weining and Bijie pilots had better rep-resentation;Anshun and Tongren pilots were more discriminating.In 2019,Jinyu838,Xin⁃zhongyu 801,Xianyu1171 had better productivity,Xianyu 1171 and Jinyu838 and Xingyu 3 had better stability;Anshun and Xinren pilots had better representa⁃tiveness,and Bijie and Weining had stronger discriminatory power.On the whole,Jingyu 838 was more productive and stable,with the best overall performance;Weining and Bijie are highly discriminating and representative in the trials.
