WHEN WOULD SEED PRODUCTION FROM CLONALLY-MAINTAINED ACCESSIONS COMPLEMENT OR POTENTIALLY REPLACE VEGETATIVE PROPAGULES? • A few points to consider…
CAN WE VERIFY THAT THE CLONE IS BEING MAINTAINED BECAUSE OF ITS SPECIFIC GENOTYPE? • Certain clones might be maintained more for convenience, fitting in with a larger, clonal management system…
DOES THE CLONE PRODUCE SEEDS THAT STORE WELL? • Two issues here: • The ability to produce seeds (sterility, dioecy) • Seed-storage characteristics
POPULATION-LEVEL CONSIDERATIONS • Is the clone a member of a larger population? • Are there other members of that population available and can the clone be mated with them?
WHEN THERE IS NO “LARGER POPULATION” • Can the clone produce apomictic seeds? • Can the clone self-pollinate? • Self-incompatibility • Inbreeding depression
