Determination of genetic variation of landraces which will be utilized in selection or crossing programs as a parent in a breeding program and determining the superior genotypes better than the existing cultivars in the target environment is required to improve the success of breeding activities. In this study, variation range for grain yield and some agronomic traits of barley (Hordeum vulgare L.) landraces were investigated during 2012/2013 cropping year at Ankara-Golbasi location, in order to determine outstanding barley landraces and to utilize them in the barley breeding programs. Two hundred barley landraces including five check cultivars (three two-rowed and two six-rowed) were used as genetic materials. The design of the experiment was Augmented Experimental Design with four blocks. Minimum and maximum values of the genotypes revealed great variation among the genotypes. The range of the values were 172–194 days for days to heading, 216–240 days for days to maturity, 82–134 cm for plant height, 204–796 for spike number per m2, 1500–7426 kg ha-1 for grain yield and 31.5–53.2 g for thousand kernel weight. The highest variation in investigated traits was observed in spike number per m2, grain yield and thousand kernel weight. Spike number per m2 had the highest effect on grain yield of landraces used in this study. As a result of evaluation in terms of grain yield and agronomic traits of landraces, it was seen that these landraces material have a potential to use for direct registration or as a genetic material in crossing programs of a barley breeding program carried out in dry conditions of Central Anatolia.
