Microsatellite analysis of Rosa damascena Mill. accessions reveals genetic similarity between genotypes used for rose oil production and old Damask rose varieties

Abstract

Damask roses are grown in several European and Asiatic countries for rose oil production. Twenty-six oil-bearing Rosa damascena Mill. accessions and 13 garden Damask roses were assayed by molecular markers. Microsatellite genotyping demonstrated that R. damascena Mill. accessions from Bulgaria, Iran, and India and old European Damask rose varieties possess identical microsatellite profiles, suggesting a common origin. At the same time, the data indicated that modern industrial oil rose cultivation is based on a very narrow genepool and that oil rose collections contain many genetically identical accessions. The study of long-term vegetative propagation of the Damask roses also reveals high somatic stability for the microsatellite loci analyzed.

Comparative GC/MS Analysis of Rose Flower and Distilled Oil Volatiles of The Oil Bearing RoseRosa Damascena

“…in the past several years it has been demonstrated by several authors that the world production of rose oil is based on a single or a very few genotypes of the world famous oil bearing rose Rosa damascena (1,2,4,11,14). The whole production of rose oil in Bulgaria and Turkey, the two main world producers of rose oil, is based on a single main genotype which has been vegetatively propagated for centuries (1,4,14).…”

“…The whole production of rose oil in Bulgaria and Turkey, the two main world producers of rose oil, is based on a single main genotype which has been vegetatively propagated for centuries (1,4,14). The last points out the necessity to extend the oil bearing rose genetic resources and genetic background for their industrial cultivation.…”

Evaluation, Genetic Diversity, Recent Development of Distillation Method, Challenges and Opportunities ofRosa damascena: A Review

“…It is assumed that the crude distillation of rose for the oil was started in Persia in the late 7 th century A.D. 5,19,71 , later on spread to the provinces of Ottoman Empire and province of Rumeli in 14 th century. The flower should be distilled immediately after harvest.…”

“…The rapid and reliable methods for understanding the genetic variation and genetic relationships of roses are the outmost important. That is why DNA markers have been applied for characterization of rose genetic diversity 5,[35][36][37][38][39][40][41][42] . Now amplified fragment length polymorphisms (AFLT) approach is a reliable, rapid and sensitive technique for detecting genetic diversity of Damask rose genotypes 34,43 .…”

“…Apart from the horticultural uses, roses hold economical import-ance owing to the essential oil in their petals as a source of natural fragrances and flavourings 4 . One of the most important Rosa species is Rosa damascena Mill of which some varieties are used for essential oil production, and others are widely cultivated as garden roses 5 . It is the national flower of Iran 6 .…”
