In order to selection of superior cold tolerant barley genotypes for cold regions of Esfahan province, this study was conducted with nine barley varieties/lines in Fereidan area, and in two successive years (2002-2004). The research was carried out in on-farm pattern experiment and in a CRB design. Results showed that grain yield and some of yield components affected by year, variety and their interactions, significantly. Positive and significant correlation observed between grain yields and numbers of spikes per square meter. Changes of numbers of spikes per square meter were main cause of grain yield variations. Grain yields correlated with thousand kernel weight, negatively and significantly. The grain yield of CB-74-2 barley line was the highest in all years, significantly. Also, the grain yield of IFN-12 and IFN-13 barley lines, selected from Esfahan province’s local varieties, were significantly higher than check variety (Makooii).
