In order to evaluate flower yield and essential oil content of Rosa damascena, 49 landraces were studied in a randomized complete block design with three replications in Sanandaj (Iran) during 2004-8. An analysis of variance revealed significant differences (p ≤ 0.01) for the number of flowers per plant, flower and petal weight, flower and petal yield per plant, essential oil ratio and essential oil yield per plant among landraces (G), years (Y) and for landrace × year (GY). The landraces of FA1, KR2, KR3, FA2, AR1 and YZ2 with 3291.9, 2526.4, 2298.7, 2239.8, 2077.6 and 1978.7 kg ha−1, respectively, produced the highest flower yield and the landraces of IS3, IS2, KR2, IS4 and FA2 with 413.25, 378.11, 364.31, 315.30 and 296.10 g ha−1, respectively, produced the highest essential oil among all of the landraces.
