This paper analysed the interaction between genotype and environment forthe 19 Populus × euramericana clones in a regional test.Their growth adaptability and geno-typic stability have been evaluted by using 8 statistics. The regression coefficient(b)and de-viation from regression meansquare(Sd2)of Eberhart-Russei model,the structural analysisparameters ai and λi of Tai model,the Ecovalence(W) of Wricke,the variarice of stability ofShulka and nonparametric measures of Nassar-Huhn wre used. The correlations amongstatistics of adaptability are highly significant and the correlations among statistics of stabil-ty are highly significant too. The correlation among statistics of adaptability and statistics ofstability are negative correlation or unsignificant.Their application regions were predictedacccording to the statistics of adaptability and stability and the effect of G×E. A number of10 super clones bave been selected.
