摘要
利用2005—2010年国家马铃薯中晚熟西北组共6组区域试验数据资料,比较LR模型和AMMI模型在品种稳定性分析上的差异。结果从LR模型分析稳定性结果看,2005—2010年‘92-24-144’的静态稳定性较高,其他大多数参试品种具有较好的动态稳定性,且年度间表现基本一致。AMMI模型分析表明,不同品种的稳定性有差异,‘青97-1-38’,‘92-24-144’的稳定性较高,‘中薯36’,‘甘L9810-18’,‘庄薯3号’的稳定性较差,年度间均表现一致;而且多数品种所表现的稳定性差异在年度间不一致。因此,AMMI模型在品种稳定性评价方面具有较高的可信度,建议马铃薯品种区域试验采用AMMI模型进行分析。
With six group data of mid-late northwest group country regional trial in 2005-2010,stability analysis of varieties was compared using LR model and AMMI model.The results showed that 92-24-144 had high static stability from LR model analysis,and the other testing varieties had higher dynamic stability and showed consistent performance in 2005-2010.The results of AMMI model indicated that there was difference in stability of different varieties.The stability of Qing 97-1-38 and 92-24-144 were higher while the stability of Zhongshu 36,Gan L9810-18 and Zhuangshu NO.3 were lower,but most varieties showed consistent performance from year to year.Therefore,the AMMI model had the higher reliability in stability evaluation of variety,which should be adopted in potatoes regional trial analysis.
