The CNAP Artemisia Project is funded by the Bill & Melinda Gates Foundation.
Research by CNAP into the genetics of Artemisia led to the first publication of a detailed genetic map in the journal Science in 2010. The map was used to facilitate rapid plant breeding in parallel with other approaches. Extensive field testing of the new varieties in the major growing regions for Artemisia enabled the selection of just a few select hybrids to be considered for commercialisation: ultimately Hyb8001r was selected as the best commercial hybrid. Following two years of independent field trials against Chinese varieties, Hyb8001r was successfully passed as a new variety by the Chongqinq Academy of Materia Medica in April 2015. A Chinese name was given to the hybrid: 药客佳蒿1号, pronounced YaoKe JiaHao YiHao - the first word sounds like York and means ‘medicine people’; the other words mean ‘good Artemisia variety’ and ‘number one in the series’.
Ongoing research and development has focused on a wider understanding of Artemisia biology, particularly in understanding the mechanism of artemisinin biosynthesis. We work with colleagues in the UK and US to achieve this objective. Current Researchers:
