Barley (Hordeum vulgare L.) is one of the most important agricultural crops in Türkiye. It is imperative to increase the
grain yield of barley to meet the growing demand. One of the most important ways to do this is to develop high-yielding
cultivars with good adaptation to varying environmental conditions. In breeding studies, the performance of candidate
lines should be determined through multiple yield trials. In this study, eighteen advanced barley lines with six check
cultivars were planted in nine locations under rainfed conditions of Central Anatolia and transitional regions in the
2019-2020 growing season. In addition to the yield performance of the genotypes, their yield stability in nine locations
was also determined. According to the result of the study, the highest and lowest-yielding locations were Konya
and Afyonkarahisar, respectively. This study revealed Sayım 40 had higher grain yield potential in Central Anatolia.
Additionally, advanced line G23 was identified as the most promising feed barley genotype yielding approximately
3959 kg/ha across nine locations in the Central and transitional ecological zones of Anatolia.
