Abstract

Genetic diversity in eight genotypes of Rosa damascena Mill. from west parts of Iran, was analyzed in a randomized complete blocks design with three replication, at the experimental field at Research Institute of Forests and Rangelandsin 2003 and 2004. Principal components analysis (PCA) and cluster analysis were applied, in order to analyze flower yield and its components including flower number, single flower weight and dry matter percentage of flower and also morphological characteristics, such as plant height, canopy, branch angel, leaf number, leaflet size, spine density and spine length. The results showed significant differences among genotypes for all of the traits. The first four components determined 87.88% (34.86%, 22.41%, 16.95% and 13.66%, respectively) of the total variation. The highest special values for flower yield belonged to the fourth component, based on which genotype of Azar-W Province could be selected for this trait. Cluster analysis classified the genotypes in 3 groups, based on the traits under study. It could then concluded from the results that a considerable genetic variation in Rosa damascena germplasm originated from west parts of the country. Also the highest heterosis could be achieved, through combining genotypes in the first and third groups.
