Drought is a major abiotic factor limiting the grain yield and yield stability of maize throughout the world therefore, the development of drought tolerant genotypes is an important breeding objective. In this study, an experimental field was conducted at Agricultural Research and Development Station Simnic in the water-stressed (2017) and non-stressed conditions (2018) to select the best performing maize hybrids. For this purpose, the new indices: RCI (the resilience capacity index), PCI (the production capacity index), YSSI (the yield susceptibility score index) and YPSI (the yield production score index) were used. The results indicated that using this new selection method, maize hybrids can be easy identified and classified in four categories of tolerance. The hybrids from category 1: HS 880- 13, HS 1158-14, HS 1156-14 were selected as combining high resilience with high productivity.
