摘　　要：使用AMMI模型对2010—2011年贵州省马铃薯区域试验结果中的产量及其农艺性状,包括株高、单株块茎数、单株主茎数、生育期、单株块茎重量进行了分析。分析结果表明,AMMI模型中的主成分轴能够解释产量、单株主茎数、单株块茎数、生育期、单株块茎质量等性状90.64%,90%,86%,82%,81%交互作用平方和,在参加贵州省马铃薯区试的11个品种中,W04-36,0402-2,米拉等品种稳定性、适应性与丰产性表现良好,W04-36可作为大面积推广种植品种,0402-7,宣薯2号,2005-1,盘薯1号,丽薯200202,威薯001号,B01-41-4产量表现一般,黑美人产量表现差。参加区试的5个试点中,通过对其鉴别力参数Di进行计算可知,毕节和安顺地区Di值大,鉴别力高,对品种具有较强选择性,六盘水地区的鉴别力最低,对品种选择性弱,适合多品种种植。The aim of this study is to use AMMI model to analyze yield and agronomic traits,including plant height,tuber quantity per plant,stem quantity per plant,mature days,and tuber fresh weight per plant,in 2010—2011 potato regional test results in Guizhou province.The study results showed that the interact principle component of AMMI model is capable of explaining 90.64%,90%,86%,82%,81% of total sum of squares of yield,tuber quantity per plant,stem quantity per plant,mature days,tuber fresh weight per plant,respectively.The species stability,adaptability and high yield ability of three varieties,W04-36,0402-2 and Mila,were better than rest species among the eleven of species tested in Guizhou potato regional test.W04-36 can be promoted and planted in large areas.Yield ability of Heimeiren was the worst among all the tested varieties.Among the five test sites,Di values of Bijie and Anshun were larger than others.Both sites have a high discriminability for variety.Liupanshui has the lowest discriminability for variety;therefore it is suitable for planting many different species.
