The objective of this study was to assess genotype by environment interaction for oil content in winter rapeseed cultivars grown in West Poland by the additive main effects and multiplicative interaction model. The study comprised of 25 winter rapeseed genotypes (15 F1 CMS ogura hybrids, parental lines and two European cultivars: open pollinated Californium and F1 hybrid Hercules), evaluated at five locations in a randomized complete block design, with four replicates. Oil content of the tested genotypes ranged from 35.2 to 48.8%, with an average of 44.55%. AMMI analyses revealed significant genotype by environmental interaction with respect to oil content. The hybrid PN66×PN18 is recommended for further inclusion in the breeding program due to its high oil content, CMS ogura line PN66 and hybrid PN68×PN18 are recommended because of its stability and high oil content.
