To select and release high-yielding and adaptable barley varieties for warm and moderate zone, are used introduction varieties containing appropriate traits(high-yielding, resistance to diseases, high quality, and adaptable) in addition to national varieties. In this study, 4 barley nurseries from ICARDA including: two yield trial and two observation nurseries were evaluated. Variance analysis of grain yield showed significant difference among genotypes. However ,none of the genotypes had a yield higher than checks in some locations. Mean comparison of yield among genotypes revealed that genotypes 6, 5 and 1 in GBYT and genotypes 19, 23 and 10 in IBYT-HI had the highest yield respectively. Observation nurseries were including: GBON and IBON-HI. In overall, taking into consideration plant height and plant type, early maturity, resistance to diseases and lodging and grain yield, from 296 evaluated genotypes, 112 entries were selected and conducted to preliminary experiments of moderate zone in next year
