AMMI模型和GGE双标图法在新疆冬小麦区域试验产量分析上的应用

摘要

[目的]客观、准确评价区域试验中冬小麦新品系的丰产性和稳定性,探明适合新疆冬小麦区域试验分析的统计模型.[方法]利用AMMI模型和GGE双标图分析2010、2011年北疆冬小麦区域试验中5个试点、12个新品系的产量结果.[结果]基因型、环境及基因型×环境互作的平方和分别占总平方和的6.96％、32.62％和26.82％,均达到极显著水平.通过模型分析,垦冬杂1号和垦冬00(2)号具有较好的稳产性和丰产性,适合在伊宁、塔城和奇台等地区种植；08/7148在安宁渠点和塔城地区种植可获得高产.同时,GGE双标图对新品系丰产性分析结果与田间试验结果趋于一致,相对于AMMI模型能够直观、简单提供新品系的稳定性和适种区域.[结论]GGE双标图法比较适合分析北疆冬小麦区域试验的结果.%[ Objective] The aim of this research is to study the yield ability and stability of winter wheat of northern Xinjiang. [ Method] In this study, AMMI model and GGE - biplot were used to analyze the data of winter wheat in Xinjiang multi - environment trials from 2010 - 2011. Twelve lines of wheat were tested in five sites. [ Result] The results showed that the proportions of the sum of squares of genotype, environment and G x E interactive effects on total sum of squares was 6. 96% , 32. 62% , 26. 8% , respectively. And there were significant effects in genotype, environment and G X E interaction. Kendongza 1 and Kendong 00 ( 2 ) had higher yield and better yield stability than other lines. 08/7148 possessed special adaptabilities, so it had promotional values in Tacheng region. Meanwhile, when comparing these two modes between AMMI model and GGE - biplot, the latter model could provide direct and simply high yield area and stability of winter wheat. [ Conclusion] The GGE - biplot model was superior to the AMMI model to analyze the Xinjiang winter wheat regional test.
