Essentially Derived Variety (EDV): Under international plant breeders' rights (UPOV and PPV&FR Act), an EDV is defined as a variety predominantly derived from an initial variety, retaining its essential genotype characteristics, generated through genetic engineering (transformation), induced mutation, somaclonal variation, or repeated backcrossing. (Correct answer)
Crossing two commercial varieties: Represents standard conventional hybridization that generates new recombinant genetic combinations, not an EDV.
Introduced hybrid: Represents an exotic germplasm introduction.
Wide hybridization with wild relatives: Pre-breeding introgression, not an EDV.
