Forty eight damask rose (Rosa damascena Mill.) accessions from different parts of Iran (11 native accessions of Kermanshah and 37 accessions from other provinces of the country) were cultivated in a randomized complete block design with three replications in Mehregan research station, Kermanshah province in 2006-2011 and their yield, morphological, and phenological traits were studied. Each experimental plot consisted of three individual plants with a distance of 3 m × 3 m. The drip irrigation was carried out once every 10 days. Also, the chemical fertilizers and pesticides were not used in the field. The desired traits were recorded and analyzed after the seedlings establishment in the third to fifth years. The results of combined analysis of variance showed that all the studied traits were significantly different (P<0.01) between the experimental years and between the different accessions. The variance of accession × year interaction in all the traits was significant (P<0.01). According to the results, the accessions Kermanshah codes 10, 11, 2, and 3, Kurdistan 1, and Isfahan codes 7 and 4 could be introduced for the cultivation in the climatic conditions of Kermanshah province as the compatible accessions with suitable flower and essential oil yield.
