ORIGIN. Common mango (Mangifera indica L.) originated as alloploid and its native home was suggested as Eastern India, Assam to Burma or possibly further in the Malay region (Popenoe, 1920).Vavilov (1926) also suggested Indo-Burma region as the centre of origin of mango.ruly wild common mango trees have been recorded in Bangladesh (Chittagong Hills), northeastern India (Assam valley) and Myanmar. Owing to its cultivation and dissemination for thousands of years, in India semi-wild trees can be found in the forests throughout the subcontinent.
