Genetic diversity of the quality in S. sclarea and development of genotypes with enhanced essential oil (EO) content have been conducted using the varieties of hybrid origin Ambra Plus (AP) and Nataly Clary (NC), both characterised by manifestation of fixed heterosis in a number of quantitative traits, including the content of EO. One hundred and twenty four inbred S2 lines in the second year of vegetation not affected by degeneration through inbreeding have been developed and assessed through forced pollination. The findings show that the improvement of quality and the development of new genotypes with extremely high content of EO supported by the valuable quantitative traits through inbreeding in S. sclarea are efficient, the inbreeding provoking phenotypic, genotypic segregation of complex hybrid populations into a wide range of genotypes, some of them being promising. The phenotype of the inbred lines derived from the studied varieties is diversified, attesting genetic segregations expressed in the diversity of the values of quantitative trait indices such as plant height, inflorescence length and structure and in the content of EO supported by these traits. Along with the inbred lines in which the content of essential oil is lower than that in the lines they originate from, lines have been produced with enhanced (1.001-1.350%) and very enhanced (1.351-1.958%) content, the latter ones making 11% of the lines derived from AP and 7% of the total number of the lines derived from NC. Inbreeding causes phenological changes: the S2 inbred lines fall into early-, mid- and late-ripening that constitutes 24, 48, 28%, respectively, in the lines derived from AP and 33% in each group of the lines derived from NC. The inbred lines with enhanced, very enhanced content of EO are valuable genotypes in view of the improvement of raw material quality and the increase of the productivity of S. sclarea cultivars.
