Plant Breeders Rights Registration in China

Our recently opened office in Kunming in China will develop the sales of plants in the Chinese domestic market. As most of the varieties in our lab are produced under an exclusive contract for the market outside China, we now offer our clients the service for PBR registration of their varieties in China. Our service will include the market research, the actual registration, the production, marketing and distribution as well as the royalty administration.
