Initial diversity of this species was enhanced by specific factors of evolution (selection, mutation, isolation), and also by ecological conditions of areas and agricultural technique of culture. Thus, local populations today are characterized by a evident diversity that deserves to be preserved and recovered and valorized. The study starts from the demands from growers and consumers, for a variety with high yield and oil potential. A new variety of thyme was created at Vegetable Research and Development Station Bacau. “Marcela” variety is characterized by the homogeneity in its phenotype. It has an erect habitus and great vigor. “Marcela” variety is a perennial subshrubs, aromatic species, distinguished by specified aroma. Strains are 0.25 – 0.38 m height. The total dry matter content of “Marcela” variety ranged from 2.57 to 3.91 (g/m2). The report between leaves and branches ranged from 59.5% to 48.1%. The highest level of essential oil yield was registered at blooming (100% of plants were in flower).
