Mango (Mangifera indica L.) is grown as one of the major fruit crops in all the countries of tropical and subtropical Africa, America and Asia pacific. As there is huge export marketing demand for mango the industrial sector depends on few of the commercial cultivars, resulting in narrowing of the genetic base and flourishing pertaining to the loss of wild species by several anthropogenetic ecological impacts. There is record of more than 60 wild Mangifera species identified in South East Asia many are now locally rare and are enclosed on the IUCN Red List categorized as Mangifera andamanica (near threatened), Mangifera camptosperma (near threatened), Mangifera casturi (extinct), Mangifera griffithii (no entries found), Mangifera indica (data deficient), Mangifera odorata (data deficient), Mangifera sylvatica (least-concern) and Mangifera zeylanica (vulnerable), although there are some conservation initiatives the biodiversity of these wild Mangifera species continue to descent. The present study was designed to vegetatively propagate M. andamanica, M. camptosperma and M. griffithii, for long-term sustainment in the gene bank. The establishment of these Mangifera species through ex-situ conservation was successful using current grafting techniques on Mangifera indica root stocks (polyembryonic) and ongoing with initiation in DNA characterisation and assessing for the purpose of breeding.
