Abstract

Rosa damascena wascollected from three parts of Kashan, and cultivated at the experimental field of Research Institute of Forests and Rangelands, using a three replicated randomized complete blocks design. Nine genotypes, were compared based on 4 different traits including petal, stamen, and pistil number and essential oil concentration, in 2002. Data were collected and analyzed using ANOVA, mean classification and cluster analysis. Genotypes showed significant differences in terms of the measured traits. Comparison of means classified the genotypes in 2, 3 and 2 groups, for petal, stamen and pistil number, respectively. Also, essential oil concentration showed a considerable genotypic variation. The areas showed significant differences in petal and pistil number. Cluster analysis classified the genotypes in two groups, based on the traits under study. The results indicated that there is not a good relationship between variation of the genotypes and geographical location. However, a considerable variation was revealed in floral parts and essential oil concentration of Rosa damascena from Kashan.
