This technique can be extended and used in
the production of foundation seed. But it has
yet to impact industrial seed production.
In countries where dioecious varieties are
in use, the male plants are pulled manually
before the harvesting machines pass through

able to develop a system of producing plant
varieties capable of meeting the technical and
legislative challenges that have presented
themselves over the past 40 years.
The scientific tools available today will
enable the development of improved varieties
with enhanced agronomic performance, while
addressing new demands from industry and
emerging markets.
There is little doubt that the coming years
will see a surge in the creation of new hemp
varieties to support the development of the
hemp industry in France and elsewhere in
Europe.
