The aim of this study is to determine an appropriate genotype for the Transylvanian Plain by analysing the responses of 17 winter triticale genotypes created at NARDI Fundulea to different weather patterns and additional nitrogen fertilisation. Field experiments were conducted at ARDS Turda over three growing seasons (2020/2021, 2021/2022, and 2022/2023). A randomized block design in six replications was used to conduct the experiments, with the first 3 replications additionally fertilized (N100 kg ha-1). Grain yield from triticale varied significantly based on nitrogen rates, weather conditions, and genotype. According to biplot analysis, the genotypes Vifor, Cordial, Utrifun, Zaraza, Zori, and Cascador consistently produced the highest yields across the three years of the study, demonstrating a lack of sensitivity to environmental interactions. With notable yield increases (more than 700 kg ha-1) over N50, the genotypes Titan, Tulnic, Zaraza, Zvelt, Zori, Stil, Vultur, and Utrifun have stood out in response to extra nitrogen fertilisation (N100). According to the evaluation of the experimental elements' interactions, the varieties Vifor, Utrifun, and Cordial were determined to be the most appropriate for the Transylvanian region.
