Abstract

To evaluate 8 Damask rose genotypes, an experiment was conducted during 2003-2004 at the experimental field of Research Institute of Forests and Rangelands, Tehran, Iran. GENETIC VARIATION was studied for phonological traits, such as flowering date and duration, and morphological traits, including plant height and canopy coverage, thorn length and density, leaflet length and width, stipule size, branch angel, receptacle length and width. Simple and combined analyses of variance, mean comparison and phenotypic correlations were performed. The combined analysis showed significant differences (P<0.01) between genotypes for all the traits and for year and year x genotype interactions for most of the traits. Comparison of means classified the genotypes for FLOWERING DURATION, and also in different groups for other characteristics. Significant correlations were observed between different traits. Also the phenotypic correlation coefficient (r= 0.90) between flower yield and FLOWERING DURATION indicates a significant (P<0.01) positive relationship between these traits. According to the results of this investigation, a wide range of variation among the 8 genotypes was observed in terms of the traits under study. for an efficient breeding program, FLOWERING DURATION could therefore, be one of the useful criteria for yield selection, though more genotypes, as well as further analyses, such as yield quantity and quality are necessary to be considered.
