In Situ and Ex Situ Conservation of Coconut Genetic Resources [PDF]

open access: yes, 2020
In situ conservation of coconut germplasm refers to the maintenance of coconut genetic diversity in the agroecosystems where it has evolved. Ex situ conservation comprises all coconut germplasm currently maintained as living trees in field genebanks, screen houses, and elsewhere beyond their host agroecosystems.
