GGE双标图在河南省夏播花生品种区域试验中的应用

笔者研究了河南省夏播花生品种区域试验中参试品种与环境的互作关系，科学评价参试品种与试点，为品种审定及试点遴选提供理论依据。采用可直观分析农作物两向数据的GGE双标图对参试品种的高产稳产性、品种与试验点环境间的关系、各试点的代表性进行了分析。结果表明：2015年河南省夏播花生品种区域试验中理想品种为‘豫花55号’，能有效地选择高产稳产品种的试点是河南省农业科学院经济作物研究所、濮阳市农业科学院、洛阳市农林科学院。

Application of GGE-biplot in Regional Test of Summer Sowing Peanut Variety in Henan Province

The authors studied the interaction between varieties and the environment in regional test of summer sowing peanut in Henan Province, and scientifically evaluated the testing varieties and pilots to provide theoretical basis for variety certification and pilot selection. The GGE-biplot software, which could visually analyze the two-dimensional data in crop, was used to evaluate the stability of high yield, the interaction relationship of varieties and environment and the representation of pilots. The results showed that the ideal summer sowing peanut variety in Henan in 2015 was ‘Yuhua 55’, and Industrial Crop Institute of Henan Academy of Agricultural Science, Puyang Academy of Agricultural Science and Luoyang Academy of Agriculture and Forestry were pilots which could effectively select high and stable yield varieties.
