Introduction Salvia L. is a very old and very widespread genus. Salvia sclarea L. (clary sage) belongs to the genus Salvia L., which comprises about 700 species and is spread throughout Europe, Asia, South and North America, Africa and Australia. In the Republic of Moldova, the genus Salvia L. is represented by 12 species [1]. The special interest for this genus, the multiple researches on its chemical composition are due to the fact that in the essential oil of clary sage have been identifi ed 160 polyphenolic compounds, some of which are unique because they are contained only in the species of the genus Salvia L. [1.]. Material and methods Testing of these plants in comparison with the control cultures was conducted on the experimental fi eld of the Institute of Genetics, Physiology and Plant Protection. The essential oil was isolated by hydro-distillation in Ginsberg devices [3]. The evaluation of quantitative characters, the phenology, the determination of resistance to wintering and drought, the productivity, the statistical analysis were performed according to the testing methods of plant varieties to the State Commission on Plant Variety Testing of the Republic of Moldova. Results and discussions In Moldova, the varieties of hybrid origin of Salvia sclarea L., which bloom and produce raw materials and essential oil in the fi rst year of vegetation and the plantations can be exploited three years, are created and homologated [2]. The varieties are distinguished by a high production of raw materials and essential oil, different periods of technical maturity, resistance to drought, frost and wintering. In the fi rst year of vegetation, the varieties Ambra Plus and Balsam form fl oral stems which are from 114.9 cm to 116.0cm tall, respectively, with long infl orescences (58.3 to 60.2 cm), compact, with a number of ramifi cations (10.5 to 13.4). These characters favour the yield structure; contribute to the synthesis and accumulation of large amounts of essential oil. The content of essential oil in the fi rst year of vegetation has values between 0.825% (dry matter) and 1.009% (dry matter). In 2012, under conditions of severe drought, the tested varieties, that were in the second year of vegetation, synthesized and accumulated a high content of essential oil, from 1.179% (dry matter) – the variety Ambra Plus, up to 1.494% (dry matter) the variety Balsam. In the third year of vegetation, these varieties accumulated a content of essential oil: from 1.029% (dry matter) to 1.078% (dry matter). The quality of essential oil is excellent due to the high content of linalyl acetate and sclareol. In three years of exploitation of the plantation, the variety Ambra Plus ensures obtaining of 24.8 t/ha of raw material and 76.1 kg/ha of essential oil. The new variety Balsam ensures a high production of essential oil - 79.5 kg/ha in three years of exploitation of the plantation. Conclusions 1. The Salvia sclarea L. varieties Ambra Plus and Balsam are resistant to drought, frost and wintering. 2. The varieties fl ourish and produce raw material and essential oil in the fi rst year of vegetation and the plantations can be exploited three years. 3. The essential oil production in three years of exploitation of the plantation is of 76.1 kg/ha at Ambra Plus and 79.5 kg/ha at Balsam.
