摘　　要： 为给云南魔芋生产中品系的选用、推广种植提供依据,对2010年云南的魔芋区域试验数据进行了主效可加互作可乘模型(AMMI模型)分析。结果表明:3条主成分轴共解释了98.73%的互作平方和,楚雄花2号为高产、稳产型品系;富源花魔芋、大关花魔芋产量一般,但稳定性好,具有广泛的适应性;丽江花魔芋产量高,但不稳产;会泽花雄芋产量及稳定性表现一般;魔花15产量一般,稳定性较差。昭通、楚雄试验点对品系的分辨力较强,昆明、永胜试验点对品系的分辨力较弱。 In order to provide basis for lines breeding and planting in Yunnan A.konjac production,the data of A.konjac regional trail in Yunnan in 2010 was analyzed with the AMMI mode1.The results showed that the three principal constituent axles explained 98.73% of G×E interaction SS.Chumohua 2 had a high and stable yield.Fuyuan and Daguan A.konjac had the commonly average yield,but they had the better stable and showed extensive adaptability.Lijiang A.konjac had a high but less stable yield,Huize A.konjac had a common and stable yield,Mohua 15 had a common and less stable yield.The experimental sites of Zhaotong and Chuxiong expressed stronger resolution power to scores,Kunming and Yongsheng expressed weaker resolution power.
