摘要
利用GenStat软件对2017年春玉米区24个中熟新品种的多点测试进行分析,基于GGE双标图模型分析表明,各试验点中以吉林省公主岭柳阳鉴定点具有较强的品种区分能力,吉林省公主岭铁北区鉴定点最具有代表性,甘肃省武威靖远县不适合作为此试验的鉴定地。GGE双标图丰产性稳产型表明,吉单37表现最为突出。基于相邻标准法分析表明,农华218、吉单37表现最好。综合分析,GGE双标图在品种产量评价方面与相邻标准法结果基本一致,且GGE双标图可以更加全面有效地评估品种和试验地点。
Field-testing is the core link of breeding. The application of scientific data analysis methods to evaluate yield tests is an effective way to identify suitable high-yielding, stable-yielding and good-quality maize varieties. GenStat data processing system was used to analyze the 24 maize varieties in the mid-maturity area in 2017.The analysis of each test point showed that the identification site in Liuyang of Jilin province has strong ability to distinguish varieties, and Gongzhuling of Jilin province was the most representative, but Wuwei of Gansu province was not suitable for the identification of this test. The GGE-biplot showed that the performance of Jidan 37 is outstanding. Use of the adjacent standard method showed that Nonghua218 and Jidan 37 performed the best. The comprehensive analysis showed that the GGE-biplot is basically the same as the results of the adjacent standard method in evaluating the yield of varieties, and the GGE-biplot could more comprehensively and effectively evaluate varieties and sites.
