Abstract
The field test changed into performed on 14 food barley genotypes along with one local and one currently released well known check (Walashe) at Fitche Agricultural research center at 2023-2024 cropping seasons. The goal was to assess the significance of genotype through environment interaction, grain yield stability, and high yielded and disease resistance genotypes in north shewa zone. The seed changed into sown in randomized completed block design (RCBD) with 3 replications within the plot size of 1.2mx3m. Effective tiller per plant (PPT) Plant height (PH), spike length (SL), days to 50% heading (DH), days to 95% maturity (DM), thousand seed weight (TSW) and grain yield (GY), flag leaf length (FLL), peduncle length (PDL) and awn length had been accrued as agronomic traits. Combined evaluation of variance detected widespread distinction among principal effect of genotypes, year and locations for maximum agronomic developments considered. The interplay impact of genotype via year, location by year, genotype by location by year imposed giant impact particularly on yield however none in all traits. Amongst evaluated genotypes, G-12 with grain yield of 3574.8kgha-1 had significantly better mean grain yield over the rest genotypes and recorded 12.6% yield benefit over standard check (Walashe). The mixed ANOVA and the AMMI analysis for grain yield throughout environments discovered significantly laid low with environments, which maintain 72.4% of the overall variation. The genotype and genotype through environmental interaction were great and accounted for 9.5% and 13% respectively. Principal component 1 and 2 accounted for 6.8% and 3.3% of the GEI respectively with a total of 10.1% variant. In typically, G-12 turned into recognized as promising genotype for grain yield, more stable, tolerant to diseases and can be used as parents for breeding purposes.
