Abstract

The evaluation of quantitative traits in lavender varieties after rejuvenation allowed the characterization and assessment of each variety. The varieties exhibited plant height ranging from 38.0 to 64.0 cm, plant diameter from 45.3 to 78.0 cm, and number of flowering stems per plant from 356 to 573 units. Regarding essential oil content in dry matter, the varieties Svetlana (5.765%) and Alba 7 (5.204%) stood out. The raw material yield ranged from 0.9 t/ ha to 2.8 t/ha depending on the variety, with the highest productivity recorded in the clone varieties Svetlana (2.5 t/ha) and Alba 7 (2.1 t/ha). The yield of the evaluated varieties and hybrids ranged from 7.9 kg/t in the semi-early hybrid Cr.13S-6-7 to 21.7 kg/t in the late-maturing variety Svetlana.
