Maize (Zea mays L.) is a strategic crop within global food, feed, and bioenergy systems, and increasing climate variability highlights the need to develop high-yielding and adaptive hybrids. This study aimed to assess the ecological plasticity, stability, and productivity of early- and mid-season maize hybrids developed by LLC “RAZT Semens-Ukraine” in order to identify the most environmentally plastic genotypes suitable for large-scale cultivation. Ecological trials were conducted in 2024 across three contrasting soil–climatic zones of Ukraine: Kyiv, Ivano-Frankivsk, and Vinnytsia regions. Grain yield was measured according to standard methodologies, while environmental index, ecological plasticity, and stability parameters were calculated using the Eberhart–Russell model. The results revealed considerable variation in yield depending on location. Among early-maturing hybrids, the highest yield was obtained from RZT Motorikks – 14.29 t/ha, while among mid-season hybrids, RZT Tekksiia demonstrated the highest productivity – 14.77 t/ha, both recorded under conditions of the Kyiv region, which exhibited the most favorable environmental index (Ij > 1). The greatest ecological plasticity was observed in RZT Motorikks (bi = 1.4), RZT Lipekks and RZT Attrakksion (bi = 1.1), as well as RZT Tekksiia (bi = 1.3) and RZT Inedikkks (bi = 1.1), indicating their suitability for intensive agricultural technologies. Meanwhile, the highest ecological stability (σd2 = 0.02) was recorded for RZT Alikks, RZT Attrakksion, and RZT Inedikkks, reflecting minimal yield response to fluctuating growing conditions.
All evaluated hybrids demonstrated high adaptive potential. However, RZT Motorikks and RZT Tekksiia are recommended for high-input production systems, whereas more stable hybrids may be advantageous in regions with variable environmental conditions. Future research should focus on multi-year testing and the integration of biotic and abiotic stress factors.
