abstract = "Interakcija genotipa i spoljašnje sredine (GEI) je kompleksan problem koji
komplikuje proces selekcije i oplemenjivanja ratarskih kultura te je stoga važno
utvrditi njenu značajnost i iskoristiti njene pozitivne karakteristike. U radu je analiziran
prinos zrna dvadeset genotipova ozimog dvoredog ječma u šest spoljašnjih
sredina (dve vegetacione sezone na tri lokaliteta). Za analizu interakcije korišćen je
linearni mešoviti model i model glavnih efekata i višestruke interakcije (AMMI) sa
AMMI1 biplot prikazom. Utvrđena je visoka statistička značajnost interakcije dok je
AMMI1 model objasnio 40.1% varijacije interakcije. Stabilnost genotipova određena
je parametrima stabilnosti AMMI modela (AMMI1, AMMI2 i ASV) i utvrđena je
značajna korelacija rangova genotipova između njih. Prinos nije pokazao značajnu
korelaciju ni sa jednim parametrom. Na osnovu Genotip Selekcionog Indeksa
(GSI), genotipovi J-82, J-103, NS-589 i J-176 su izdvojeni kao široko adaptabilni
i superiorni u pogledu prinosa i stabilnosti što je potvrđeno i biplot prikazom.
Genotipovi koji su na osnovu AMMI1 procenjenih vrednosti prinosa preporučeni
za svaki od lokaliteta su najprinosniji NS-525, NS-593, J-176, NS-589, J-103 i J-82.
Razlike u interakcijskom efektu između godina (Zemun Polje i Zaječar) kao i slab
diskriminatorski efekat (Kragujevac) ne izdvajaju ni jedan lokalitet kao pogodnu
test lokaciju. Winner pristupom, sve ispitivane sredine možemo smatrati kao jednu
mega-sredinu što ukazuje da u ogledu dominiraju nepredvidive interakcije što specifične
adaptacije čini manje značajnim. AMMI1 model je pouzdan i informativan u
interpretaciji interakcije i ništa se značajno neće promeniti ako se druga interakcijska
komponenta naknadno uključi. Izdvojene su neke inbred linije ječma što ovaj model
čini pogodnim u selekciji perspektivnih genotipova., Genotype by environment interaction (GEI) is a complex problem which complicates
the selection and breeding process of field crops, and therefore it is important
to determine the significance and take advantage of GEI. The paper analyzed the
grain yield of twenty genotypes of winter two-row barley in six environments (two
growing seasons in three localities). A linear mixed model and additive main effects
and multiplicative interaction (AMMI) model with AMMI1 biplot display were
used for interaction analysis. High statistical significance GEI was determined and
AMMI1 model was explain 47% of interaction. The stability of the genotypes was
estimated by different AMMI stability parameters (AMMI1, AMMI2 and ASV) and
a significant correlation was established between them. Grain yield and stability were
not related. Genotypes J-82, J-103, NS-589 and J-176 were selected as superior and
wide adaptability using Genotype Selection Index (GSI). They highlight as stable and
high yielding which was agreement with results of biplot analysis. On based AMMI1
estimates of grain yield, the genotypes recommended in each of the localities were the
most yielding NS-525, NS-593, J-176, NS-589, J-103and J-82. The difference in the
interaction effect by year (Zemun Polje and Zaječar) and weak discriminating effect
(Kragujevac) does not sepatare any suitable test location. By winner approach, all the
examined environments can be considered as one mega-environment, which indicates
that unpredictable interactions dominate in this research, due to which specific
adaptations were not of high importance. AMMI1 model is reliable and informative
in the interpretation of the GEI which indicates that essentially nothing happens when
the second interaction axis is subsequently included. Some inbred lines of barley have
stood out, which makes this model suitable for the selection of perspective genotypes.",
