In Switzerland, the climate of Ticino is best suited for the cultivation of rosemary (Rosmarinus officinalis L.). This study aimed to identify and to characterise clones adapted to the conditions of Ticino. Forty-three clones were collected from mother plants older than 15 years and from an altitude between 250 and 1010 m. Each clone was cultivated at two sites (Gudo, 280 m, and Olivone, 900 m). Agronomic aptitudes, contents of essential oils and their chemical composition were analysed. The agronomic aptitude of rosemary clones showed a high genetic variability. The two sites’ mean content of essential oils was 1.98% and 2.3%, respectively. Chemical analysis distinguished four groups: 1) a group of camphene, 2) of 1,8-cineole and â-pinene, 3) of bornyl acetate and limonene, 4) of á-pinene and verbenone. None of the clones resisted winter at Olivone.
