The effect of gene,environment and their interaction on the yield per unit area of peanut was analyzed to evaluate the stability of peanut varieties and their discriminating ability of places.AMMI model was adopted to analyze the experimental data of the peanut tested in Jilin in 2011.Three principal constituent axles explained 92.05 % interactive average peanut yield.The results showed that ’06ceB8’,’Jihua08-39’ and ’Puhua28’ were high and stable yield varieties and they were extensively adaptable.’Yinzhong08ceA2’ and ’2008-8’ were higher average yield and bad stability.’Baisha1016’ was lower average yield and better stable.The results also indicated that varieties in the test locations of e2,e3 and e6 expressed stronger resolution power;e4 and e5 expressed weaker discriminating ability.AMMI model can be used to evaluate stability and adaptability of peanut varieties as well as explicitly analyze interaction between environment and gene.This study established the foundation for statistic methods used to objectively evaluate productivity and stability of peanut varieties in short period.
