基于AMMI模型和GGE双标图的玉米区域试验分析

Analysis of the Maize Regional Experiment Based on the AMMI Model and GGE Biplot

为了明确甘肃省2013年玉米区域试验参试品种的丰产性和稳定性,为玉米品种的推广提供参考,选用2013年甘肃省中晚熟组玉米品种区试参试14个品种(系)、5个试点的试验数据,利用基于R语言的AMMI和GGE双标图分析参试品种的丰产性和稳产性以及试点环境的区分力和代表性。结果表明,高产品种为泰玉1028、五谷568、龙博士7号、SN318,理想区试点是酒泉和武威。综合分析2种模型,高产又稳定的理想品种为龙博士7号。SN318适宜在酒泉种植,泰玉1028、五谷568、龙博士7号适宜在武威、张掖地区种植。AMMI模型与GGE双标图可以合理有效地评估品种(系)和区域。

In order to clarify the yield potentials and stabilities of maize varieties in the 2013 regional experiment in Gansu Province so as to provide reference for the promotion of maize varieties,using the test data of 14 varieties(lines)in 5 sites in the regional experiment of mid-late maturity maize varieties in Gansu Province in 2013,the AMMI and GGE biplots models based on R language were used to analyze the yield potentials and stabilities of the tested varieties,as well as the discrimination and representativeness of the site environment.The results showed that the high yield varieties were Taiyu 1028,Wugu 568,Longboshi 7 and SN318,and the ideal site was Jiuquan and Wuwei.Based on the comprehensive analysis from the two models,the ideal variety with high yield and stability was Longboshi 7.SN318 was suitable for planting in Jiuquan,Taiyu 1028,Wugu 568 and Longboshi 7 were suitable for planting in Wuwei and Zhangye regions.AMMI model and GGE biplot could reasonably and effectively evaluate varieties(lines)and regions.
