Stability of grain yield performance of winter wheat genotypes

Bread wheat is one of the most represented field crops whose level and stability yield very important for food security in Republic Serbia. In paper was investigated expression 15 winter bread genotypes different agroecological conditions Serbia, using Additive main effects multiplicative interaction (AMMI) model GGE-biplot method analysis. Aim investigation to determine which applied analysis superior identification desirable cultivation given environments. Analysis variance showed that genotype genotype-environment (G×E) represent highly significant sources variability grain yield. AMMI GGE analyses were point out similar results an indisputable conclusion multienvironment trials, besides routine usage variance, must be analized with this two models, combine PCA simpler interpretation closer concept view agronomical trial, while more complex gives precise "which-won-where", i .e. defining narrowly adapted Thus, G11 as highest average narrow environment Sombor can recommended, well 2 (Kruševac), modest requests (G2) rather recommended 1 (Kragujevac), characterized by less fertile soil a smaller amount uneven distribution precipitation.
