Stability of yield or of any other trait depends on the ability of a given cultivar to response to
changes in the environment, which is also referred to as phenotypic plasticity. The analysis of a
genotype × location interaction is necessary to obtain information on the stable performance of
genotypes. This paper presents results of the genotype (G) main effect and the genotype by
environment (GE) interaction, genotype plus genotype by environment interaction (G × GE)
biplot analysis of a multi-environmental trial with eight maize hybrids of the FAO maturity
group 600 and six different locations in Serbia conducted in 2018. The objective was to
determine the effects of genotypes, six environments and their interactions on grain yield and to
identify stable maize genotypes. The trial was set up in a randomised complete block design with
three replications in each environment. The combined ANOVA indicated that the main effects of
environments, genotypes and the genotyp...e by environment interaction were highly significant.
The G × GE effects were further partitioned using a GGE biplot model. In the FAO maturity
group 600, the first mega-environment contained environments E6 (Požarevac), E5 (Pančevo)
and E2 (Bečej) with a check G7 (ZP EXP1) producing the highest yield. The mega-environment
contained environments E4 (Sremska Mitrovica) and E1 (Zemun Polje) with the most yielding
hybrid ZPSC 606. Genotypes G8 (ZP EXP2) and G7 (ZP 707) are considered to be the “ideal”
genotype in terms of performance and stability.
