Plant Breeders’ Rights are only granted where the plant variety is (a) novel, (b) distinct, (c) uniform and (d) stable.
Novelty refers to the newness of the variety. Unlike in the case of patents, absolute novelty is not a requirement for Plant Breeders’ Rights; a variety is considered to be new if propagating material has not been made available in South Africa for longer than 1 year and also has not been available in other countries for more than 4 years (6 years for trees and vines).
A plant variety is distinct if some characteristics are clearly distinguishable from any other plant variety of the same kind of plant.
The plant variety should be sufficiently uniform with regard to its characteristics; all plants in a variety should look alike.
A plant variety is stable when the unique characteristics remain unchanged after repeated propagation.
