The main objective of this study was to evaluate genotype-by-environment interactions in a spring barley germplasm panel with different geographic provenance and to identify useful germplasm that can be exploited in the barley breeding program. Spring barley genotypes usually show wide variation under climatic conditions in the south-east of Romania, which negatively affects agronomical traits. During the 2021-2023 period, at National Agricultural Research and Development Institute (NARDI) Fundulea, a spring barley panel was tested under three different environments, and data of heading (DH), data of flowering (DF), plant height (PLH), yield (Y), one thousand kernels weight (TKW), protein (P) and starch (S) content were determined. The significant genotype × environment interaction on the traits showed different responses of the genotypes across the testing environments, offering the possibility of identifying some genotypes of interest for future crosses and describing the genetic resources for stakeholders.
