Barley production in rainfed areas faces challenges from climate variability, with severe hot winds and high temperatures during grain filling which are causing yield declines in Uzbekistan. This study evaluated the agronomic performance and yield stability of eight barley varieties and accessions under rainfed conditions during 2022-2023 growing seasons. Field germination increased from 29.2-36.5% in 2022 to 57.8-75.5% in 2023 due to better moisture availability. Plant height ranged from 57-75 cm, while tillering capacity varied from 1.6-2.8 tillers per plant. Grain yield improved dramatically from 0.3-0.5 t/ha in 2022 to 1.8-2.8 t/ha in 2023. Variety Ang'iz demonstrated superior performance with the highest yield (2.8 t/ha), followed by HM-12-20 and KP-24 (DNS-4) with 2.4-2.5 t/ha. The results revealed significant genotype × environment interactions affecting all agronomic traits, highlighting Ang'iz as a promising candidate for rainfed production systems and breeding programs.
