Product information is based on data from the 2011/2012 Regional Trials for Intermediate to Late Maturing Populations from CIMMYT evaluated at 25 locations in Southern Africa (ILPOP12). Actual performance will vary depending on a number of agronomic and environmental factors.
CIMMYT grants licenses to pursue varietal registration of OPVs to qualified public-sector partners. Following successful varietal release in a country, commercial licenses may be issued to private-sector partners by CIMMYT or the varietal registrant on a non-exclusive basis, subject to the terms of the license issued to the varietal registrant.
Private-sector partners interested in commercializing a CIMMYT-derived OPV in a country where the product has not yet been released are encouraged to approach a qualified public-sector partner who may apply to CIMMYT for a varietal registration license.
