基于GGE双标图对江苏省大麦鉴定试验品种的高产稳产和适应性分析

Analyses for high-yield, stability and adaptability of barley varieties in identification test of Jiangsu province using GGE biplot

以2014~2015年江苏省大麦鉴定试验的14个品种在8个试验点的产量数据为材料,采用GGE双标图法分析参试品种的高产、稳产和区域适应性。基于对试验点的区分力和代表性分析发现,尽管各个试验点在区分力方面存在一定的差异,但均具有较强的代表性。通过对参试品种的高产性和稳产性分析,发现苏B1202和连啤9091在区域试验中具有较好的高产性和稳产性,且适宜种植的试验点较多,具有一定的广适性,是大麦生产上具备推广潜力的理想品种。

The features of high-yield,stability and regional suitability of 14 barley cultivars were evaluated using the yield data at eight test sites in Jiangsu province from 2014-2015 through the method of GGE Biplot.According to the evaluation of discrimination and representativeness for test sites,all these sites were highly representative,although there was difference in the discrimination among them.The result of mean vs.stability view suggested that SuB1202 and Lian-Pi9091 possessed more prominent high-yield and excellent stability than other varieties.In addition,both of them had the feature of wide adaptability and were ideal varieties for barley production.
