abstract = "Bread wheat is one of the most represented field crops whose level and stability of yield is very
important for the food security in Republic Serbia. In the paper was investigated stability of yield
expression of 15 winter bread wheat genotypes in different agroecological conditions of Serbia,
using the Additive main effects and multiplicative interaction (AMMI) model and GGE-biplot
method of analysis. Aim of investigation was to determine which of applied analysis is superior
in identification of the most desirable genotypes for cultivation in given environments. Analysis
of variance showed that genotype and genotype-environment (G×E) interaction represent highly
significant sources of variability in expression of grain yield. AMMI and GGE analyses were point
out similar results and an indisputable conclusion is that multienvironment trials, besides routine
usage of analysis of variance, must be analized with one of this two models, which combine
analysis of variance and PCA analysis. AMMI analysis is simpler for interpretation and closer to
the concept of view of the agronomical trial, while GGE analysis is more complex and gives more
precise interpretation of “which-won-where“, i.e. for defining of narrowly adapted genotypes in
given environments. Thus, G11 as the genotype with highest average yield is narrow adapted to
the environment Sombor and can be recommended, as well as in the environment 2 (Kruševac),
while genotypes with modest requests (G2) rather can be recommended for cultivation in the
environment 1 (Kragujevac), which is characterized by less fertile soil and a smaller amount and
uneven distribution of precipitation., Hlebna pšenica je jedna od najzastupljenijih ratarskih vrsta, čiji je nivo i stabilnost prinosa
veoma važan za prehrambenu sigurnost Republike Srbije. U radu je ispitivana stabilnost ekspresije
prinosa zrna 15 genotipova ozime hlebne pšenice u različitim agroekološkim uslovima Srbije,
korišćenjem AMMI modela i GGE-biplot analize. Cilj je bio da se utvrdi koja od primenjenih
analiza je superiornija u identifikaciji najpoželjnijih genotipova za gajenje u datim sredinama.
Analiza varijanse je pokazala da genotip i interakcija genotip-sredina (G×E) predstavljaju veoma
značajan izvor varijabilnosti pri ekspresiji prinosa zrna. AMMI i GGE analize su dale slične rezultate,
pa je nesporan zaključak da je neophodno višelokacijske oglede, pored analizom varijanse
koja se najćešće rutinski koristi, analizirati i jednim od ova dva modela, koji kombinuju analizu
varijanse i PCA analizu. AMMI analiza je jednostavnija za interpretaciju i bliža je agronomskom
konceptu poimanja ogleda, dok je GGE analiza kompleksnija i jasnija za interpretaciju gde ko
pobeđuje, odnosno za definisanje usko prilagođenih genotipova datim sredinama. Tako G11, kao
genotip sa najvećim prosečnim prinosom je usko prilagođen lokaciji Sombor, pa se prevashodno
može preporučiti toj lokaciji ali i lokaciji 2 (Kruševac), dok se genotipovi skromnijih zahteva
(G2) pre mogu preporučiti za gajenje u lokaciji 1 (Kragujevac), koja se odlikuje lošijim zemljištem
i manjom količinom i lošijim rasporedom padavina.",
