Sunflower has been proposed as a potential crop model for an adaptation to a changing environment and
special attention should be paid to testing hybrids under different environments. Additive main effects and
multiplicative interaction model (AMMI) supplemented with genotype main effects and genotype by
environment interaction effects (GGE) were used for dissection of genotype by environment interaction and
evaluation of hybrids and testing environments. The research included 24 sunflower hybrids grown across
twelve environments. AMMI analysis identified four significant interaction principal components (IPC), while
in GGE biplot the first two IPCs accounted together for 44.59%. Environmental factors contributed the
largest proportion in the total variation of seed yield (67.40%), followed by interaction and genotypes. High
yielding hybrids H1, H14 and H11 showed specific adaptation to environments E10 and E1, respectively. The
average environment coordination (AEC) view of GGE biplot indicated H17 as the most desirable genotype
regarding seed yield. From the results of this study it can be concluded that MET trials are important not just
for evaluation of stability and choosing the most stable genotypes, but also the genotypes that will perform well
in low yielding environments and be able to take advantage of the favourable environmental conditions.
