Damask rose (Rosa × damascena Herrm.) is the most important scented rose species, which some of its varieties are great importance for rose oil production. In the present survey, a total of 327 accessions of wild Damask rose from 21 geographically distinct regions of Iran were collected and transplanted in a protected conservation garden. After 2 years of plants establishment, phenotypic variation of accessions were evaluated using 36 morphological traits. High level of phenotypic variations was detected among the accessions especially desirable variations for commercial characters such as petal color, number of petals, and fragrance. The highest variability corresponded to petal number, leaf color, leaf stipule, and prickle shape. Flowering date varied from 08 May to 03 June. The petal number ranged between 17 and 159. The highest values for flower weight and petal weight were 5.67 and 4.61 g, respectively. Leaflet length ranged from 20.09 to 60.73 mm, while leaf width varied from 15.26 to 44.75 mm. Regression analysis indicated the importance of petal color, flowering date, and leaflet width/length in influencing floral scent. Dispersion diagram based on the first two principal components (40.86% of total variance) showed that the studied accessions were distributed into the plot. Some of the superior accessions were separated from others in scatter plot and characterized by the highest value of flower weight, petal weight, and petal number. In conclusion, the genotype collected will be useful for ex situ conservation and utilization in breeding programs of Damask rose.

锦缎玫瑰（罗莎 × 大马士革赫尔姆（Herrm。）是最重要的玫瑰香型，其中某些品种对玫瑰油的生产非常重要。在本次调查中，从伊朗21个地理上不同的地区收集了总共327份野生锦缎玫瑰，并将其移植到一个受保护的保护花园中。建立植物2年后，使用36种形态性状评估了种质的表型变异。在种质中检测到高水平的表型变异，特别是对于商业特性而言理想的变异，如花瓣颜色，花瓣数量和香味。最高的变异性对应于花瓣数量，叶片颜色，叶片托叶和刺皮形状。开花日期从5月08日至6月03日不等。花瓣编号在17到159之间。花重和花瓣重的最高值分别为5.67和4.61 g。小叶长度为20.09至60.73 mm，而叶宽为15.26至44.75 mm。回归分析表明，花瓣颜色，开花日期和小叶宽度/长度在影响花香中很重要。基于前两个主成分的色散图（占总方差的40.86％）表明，所研究的种质已分布到样地中。在散点图中，一些上等种质与其他种质分开，并且以花重，花瓣重和花瓣数的最大值为特征。总之，收集的基因型将有助于锦缎月季育种计划的异地保存和利用。叶宽从15.26毫米到44.75毫米不等。回归分析表明，花瓣颜色，开花日期和小叶宽度/长度在影响花香中很重要。基于前两个主成分的色散图（占总方差的40.86％）表明，所研究的种质已分布到样地中。在散点图中，一些上等种质与其他种质分开，并且以花重，花瓣重和花瓣数的最大值为特征。总之，收集的基因型将有助于锦缎月季育种计划的异地保存和利用。叶宽从15.26到44.75毫米不等。回归分析表明，花瓣颜色，开花日期和小叶宽度/长度在影响花香中很重要。基于前两个主成分的色散图（占总方差的40.86％）表明，所研究的种质已分布到样地中。在散点图中，一些上等种质与其他种质分开，并且以花重，花瓣重和花瓣数的最大值为特征。总之，收集的基因型将有助于锦缎月季育种计划的异地保存和利用。基于前两个主成分的色散图（占总方差的40.86％）表明，所研究的种质已分布到样地中。在散点图中，一些上等种质与其他种质分开，并且以花重，花瓣重和花瓣数的最大值为特征。总之，收集的基因型将有助于锦缎月季育种计划的异地保存和利用。基于前两个主成分的色散图（占总方差的40.86％）表明，所研究的种质已分布到样地中。在散点图中，一些上等种质与其他种质分开，并且以花重，花瓣重和花瓣数的最大值为特征。总之，收集的基因型将有助于锦缎月季育种计划的异地保存和利用。
