One of the main breeders tasks is improving characteristics of existing varieties and creating new genetic variability, which will achieve better economic effect. By observation of genotypes in different environmental conditions and by assessment of their interaction ideal genotypes for specific growing area will be chosen. The aim of this study is evaluation of genotype/environment interaction for plant height and grain weight per spike, grown solonetz and chernozem. The experiment was set in two different agro-ecological locations, Kumane (Banat) on solonetz soil and on Rimski Šančevi, chernozem. During two growing seasons 2013/2014 and 2014/2015 three genotypes of bread wheat: NSR-5, Pesma and Renesansa were examined. Based on an interaction between genotype and agro-ecological environment for plant height and grain weight per spike, presented trought AMMI1 biplot, it was noted that the genotypes differed more in multivariate part of the variation then in an additive effect.
