Abstract

Rosa damascene Mill. wascollected from west parts of Iran, and cultivated at the experimental field of Research Institute of Forests and Rangelands, using a three replicated randomized complete blocks design. Seven genotypes, were compared for essential oils yield in 2003  and for petal, stamen, and pistil number, in 2003-2004. Genotypes showed significant differences in terms of the measured traits. Comparison of means classified the genotypes in 7, 7 and 7 (in 2003) and 6, 7 and 6 (in 2004) groups, for petal, stamen and pistil number, respectively. Also, essential oils concentration and yield showed genotypic variation. A considerable variation was, therefore, revealed from different analyses in floral parts and essential oils concentration of Rosa damascena Mill.  from west parts of Iran.
It could then be concluded from the results of different analyses that although the genotypes could be grouped based on geographical origins, concentration and yield of essential oils as the most important product of Rosa damascena Mill., and also some of the related traits, such as floral parts could be used as appropriate selection factors for classification of damask rose genotypes, in order to use in breeding program.
