Rapeseed trials performed in the period 2007-2010 were analyzed to evaluate seed and oil yield stability in NS rapeseed cultivars in changeable environmental conditions of northern Serbia. Seed yield, oil content and yield for 40 winter and 9 spring rapeseed cultivars were analyzed. It was found that the influence of year on seed and oil yield was most significant. Genotype (cultivars) by environment (year) interaction was further analyzed using AMMI (Additive Main Effects and Multiplicative Interaction) model. In the environmental conditions present during the trial in Rimski Sancevi, according to the analysis of regression coefficient (bi) and ecovalence (Wi) and AMMI model, winter cultivars Nena and NS-L-102 were the most stable and high seed yielding, and hybrid cultivar NS-H-R-3 was singled out for oil yield. These cultivars are recommended for implementation in future breeding programs and for growing in the conditions described in this paper.
