Abstract
In genotype by environment interaction estimation, as well as, in total trial variability anal­ysis several models are in use. The most often used are Analysis of variance, Eberhart and Russell model and AMMI model. Each of the models has its own specificities, in the way of sources of varia­tion comprehension and treatment. It is known that agriculturally less productive environments increase errors, diminish reaction differences between genotypes and decrease repeatability of conditions during years. A sample consisting on six bread wheat varieties was studied in three veg­etation periods on halomorphic soil, solonetz type in Banat (vil. Kumane). Genotype by environ­ment interaction was quantified using ANOVA, Eberhart and Russell model and AMMI model. The results were compared not only on pure solonetz soil (control), but also on two level of ameliora­tion (25 and 50t/ha phosphor-gypsum).
