The evaluation of Elymus hispidus var. hispidus ecotypes in different ecological zones of Kurdistan province was carried out at Baharestan Agricultural Research Station in order to nomination of the best ecotypes in terms of adaptability and establishment. The experiment started in 2010 and continued to 2015. For each Ecotype adequate seed of different stocks in whole of the province was reaped. In reproduction phase (2010 autumn) and after soil preparation, all ecotypes were planted on plots with 5*6 m2. In 2011 and 2012autumn, the Ecotype of each Species based on complete randomized block design with 3 replications and 2 meter intervals on 2*4 m2 plots and 4 lines with 4-meter length and 50 cm intervals (In order to elimination of marginal effects) planted. The measured traits for plant selection were 1) growing 2) flowering 3) seeding 4) Yield 5) canopy cover 6) height and 7) regrowing, all data were statistically compound analyzed by SPSS and averages were compared using Duncan method. Results showed that there were significant differences among the measured traits and ecotypes (P≤0.05) in all studied years (2012-2015). In terms of measured parameters for all ecotypes of Elymus hispidus var. hispidus, Dolab Ecotype, showed superiority in the Baharestan research station conditions. it seems that altitude, soil properties and aspect factors have had most efficacy on different ecotypes operation of this specie in this study.
