Profitable and sustainable maize production is based on the use of stable and performing hybrids, suitable for contrasting environmental conditions. This paper presents the behaviour of three commercial maize hybrids at ARDS Șimnic- Craiova, Dolj County, in the period 2017-2020. The results of the ANOVA showed that the hybrid, year, and interaction H Y had significant effects on grain yield. The major variation of grain yields (80%) was caused by the year, the highest yields being obtained in 2018 and 2020, while the lower grain yields were obtained in 2017 and 2019. Average grain yields, variation coefficients (CV), regression coefficients (b), intercept values (a) and determination coefficient values (R2) of hybrids were examined as stability parameters. The yield stability analysis indicated that the Iezer hybrid has a good adaptability to unfavourable environmental conditions from the study area, the P 0216 hybrid has a good adaptability to favourable environmental conditions, and the P 9637 hybrid has a good adaptability to contrasting environmental conditions.
