The aim of the research was to determined the forage yield potentials of the some smooth brome- grass (Bromus inermis Leyss.) clones in dryland conditions of Trakya Region of Turkey. Sixty three smooth bromegrass clones were used a material in the research. The experiment were carried out as randomised complete block design with three replications at Tekirdag Namik Kemal University Agricultural Faculty Field Crops Department experimental area in 2012-2014 years. In this research was determined fresh and hay yield of smooth bromegrass clones in dryland conditions. Clones were cut one times at first year and two times at second year during growing period. The results showed that fresh and hay yield were found to be statistically significant differences (P<0.01) between smooth bromegrass clones. Total fresh yield of smooth bromegrass clones were between 839.67 - 4182.00 kg/da and 1673.67 - 6922.67 kg/da for 1st and 2nd years, respectively. Total hay yield was between 216.67 - 1546.33 kg/da and 540.00 - 2279.33 kg/da for 1st and 2nd years, respectively. Best performances were determined from clones 315383-I, 325227, 325230-II, 345596, 419583, 440190, 502312-II, 538824, 547400-III, 578545 and 578545-II in dryland conditions. These clones with high yield can be used as parents in policrosses to develop synthetic cultivar.
