The aim of this study was to examine the magnitude of genotype × environment (G × E)
interaction for the grain yield and grain oil content in soybean genotypes from the collection
of Maize Research Institute Zemun Polje and to identify stable sources for breeding for these
traits. Fourteen soybean genotypes from maturity group 00 were tested in the field trials set
up over two years, at two locations (Zemun Polje and Pancevo), according to a completely
randomized block design. After harvest, the oil content in the grain was measured on a NIRT
(near infra-red transmission) analyzer. Interaction G × E for grain yield and oil content was
evaluated by the application of AMMI-1 (additive main effects and multiplicative interaction)
model. A great portion of the variation (80.91%) of G × E interaction for the grain oil content
in soybean genotypes was explained by the first interaction axis of the AMMI-1 model. Eight
genotypes were distributed close to the stability line. The most ...important among them where
two cultivars with above the average oil content and high stability, as well as the Agassiz
variety, with a maximum average value of this parameter, expressing small interaction with
environment. AMMI analysis for grain yield revealed that first interaction axis had explained
55.3% of the variation of G × E interaction for this trait. The largest number of genotypes
achieved grain yield similar to the general average, with various interaction effects. The most
stable grain yield was noted for Maple Presto variety, while the Olima, Evrika, PI 180507 and
Kabott genotypes showed satisfactory stability. Cultivars Korana and Krajina proved to be
superior to other genotypes, both in terms of yield and stability, confirming that domestic
genotypes had adaptation to local agro-ecological conditions as compared to introduced ones.
