Some sugarcane varieties can be supplied to all users, as they are freely distributed varieties not covered by royalties. Other varieties are strictly reserved for exchanges between sugarcane breeding centres, or are covered by special contracts between the plant breeder and the user.

Guarantee of intellectual property rights

Visacane  guarantees variety dissemination that safeguards plant breeders' rights. Variety suppliers are ensured that their varieties are disseminated throughout the world in total respect of their terms of use and property rights.

Appropriate contracts

CIRAD offers its partners contracts suited to each situation, so that plant breeders' intellectual property rights over the varieties are respected. The permitted uses of transferred planting material are precisely fixed. The rules for publications on work in which the planting material might be used are specified, as are the property and exploitation rights for results obtained using the transferred material.
