Abstract. The oil-bearing rose (Rosa damascena Mill.f.trigintipetala Dieck) is of priority economic importance to Bulgaria, whose products are entirely export oriented. The main limiting factor for its development are meteorology conditions throughout the growing season. These abiotic factors have exerted a growing influence in recent years, resulting in reduced production traits. The direction of the selection of the oil-bearing rose is associated with offering high-variety, selection of promising branches resistant to abiotic stress. Given the rich gene fund of the assembly origin, variety, hybrids at the Institute of Roses, Essential and Medical Cultures, Bulgaria, a lection program has been developed that reflects the main stages of research.
