- W100334967 abstract "本文介绍一种分析作物区域试验结果的方法-GGE叠图法。首先,将原始产量数据减去各地点的平均产量,由此形成的数据集只含品种主效应G和品种-环境互作效应GE,合称为GGE。对GGE作单值分解,并以第一和第二主成分近似之。按照第一和第二主成分值将各品种和各地点放到一个平面图上即形成GGE叠图。借助于辅助线,可以直观回答以下问题:(1)什么是某一特定环境下最好的品种;(2)什么是某一特定品种最适合的环境;(3)任意两品种在各环境下的表现如何;(4)试验中品种×环境互作的总体模式是怎样的;(5)什么是高产、稳定品种;(6)什么是有利于筛选高产、稳定品种的环境。" @default.
