Cultivation and processing of aromatic and medicinal plants (AMP), to be used for maintaining and improving health, are in continuous development in our country. Research on the species Salvia sclarea L. and Lavandula angustifolia Mill, using modern methods, was initiated at the Research Station for Aromatic Plants and Essential Oils. Since 1996, research of major importance in the field of genetics and breeding of aromatic and medicinal plants, as well as the creation of promising genotypes has been conducted at IGPPP. The cultivation of these species is particularly advantageous due to the cultivars of aromatic and medicinal plants that in droughty years produce higher amounts of good quality essential oil than in the years with normal amount of atmospheric precipitation. Our research was aimed at determining the best uses of aromatic and medicinal plants, the creation and evaluation of new genotypes of aromatic and medicinal plants, the development of cultivars and hybrids adapted to the climatic conditions of the Republic of Moldova, with superior characteristics not only from the point of view of productivity, but also of the quality of the raw material, of the essential oil, due to the high concentration of active principles; maintaining, reproducing and implementing new cultivars. Purpose. The importance of aromatic and medicinal plants is determined by the multiple uses of essential oils in medicine, perfumery, cosmetics, aromatherapy, food etc.; for this reason, research was focused on the diversification of the initial breeding material, the improvement of the assortment of hybrids and cultivars. Genetics and breeding, as well as creation of new cultivars and hybrids is a continuous process. Each newly approved, patented cultivar is more efficient than the previous ones.
