Contract Growing
Hybrid and open-pollinated vegetable seed crops grown under contract. Field location, isolation distance, and grower selection matched to the specific requirements of each variety.
Quality & Documentation
Roguing, detasseling, field inspection, and harvest supervision are managed directly. Seed lots are tested and documented to meet germination, purity, and moisture specifications.
Production Locations
California production for climate-sensitive crops. International production available through Orsetti's established network for species requiring specific day-length or temperature profiles.
Services
Production contracts
built on forty years.
Seed production is where genetics become inventory. A variety that performs in trials produces nothing unless it can be multiplied reliably and at scale. That gap — between a good line and a commercially available lot — is where production contracts matter.
Orsetti has managed production for its own research program since 1985. We apply the same field supervision, isolation protocols, and quality documentation to contract work. Every finished lot is tested before it moves.
Parental lines and finished seed remain the property of the contracting party. Orsetti provides the production infrastructure, management, and quality assurance.
