Abstract: Since the development of the selection program for Artemisia annua L. hybrid lines of high artemisinin content and agricultural improvement within the program at CPQBA-UNICAMP, new selections have been annually evaluated for biomass yields, rates between leaves and stem, artemisinin content, and essential oil (composition and yields). Among the genotypes were evaluated during the period of November, 2000, to March, 2001, at CPQBA-UNICAMP, in Campinas-SP, Brazil, artemisinin ranged from 1.69 to 2.01 g/m2. The essential oil yield and composition of a population cultivated in large-scale exhibited variations by phenologic stages: at booming, 0.40 %; in mid flowering, 0.30 %; and close to senescence stage 0.21 %. In the same phenological stages, some of the major compounds of essential oil also varied, respectively: 1, 8 cineole, 17.06 %, 21.88 %, and 28.6 %; camphor: 28.44 %, 14.89 % and 30.87 %. The results provide parameters to develop raw material with antimalarial applications as well as to characterize the essential oil obtained from large-scale cultivation.
