There is no record of when mangoes were first introduced to Hawaii, but several strains called Hawaiian mangoes have been cultivated for many years. These were polyembryonic (see Mango-pedia, Morphological Traits > Mono- and Polyembryonic Mango) strains.
The first recorded introduction was around 1825, when mangoes were brought in by the Westerners from various regions via multiple routes, including the Philippines, Chile, Mexico, and southern China. In addition, in 1899, the Portuguese introduced Indian cultivars as grafted seedlings along with grafting techniques. Until then, mango cultivation in Hawaii had been done on a small scale, growing seedlings from seeds in gardens, but with the introduction of grafting technology, it expanded dramatically.
In the 1900s, improved varieties from Florida, also in the United States, were introduced. Most of the monoembryonic mangoes grown in Hawaii today are cultivars introduced from Florida. Ref: Hamilton (1993).
Records indicate that a monoembryonic cultivar called 'No. 11' was brought to Florida from Cuba by seed in 1861. Of these, a seedling line from 'Mulgoba' was selected for its superiority and named 'Haden' in 1910. 'Haden' became the most important mango cultivar in Florida and was used as a breeding material and became the parent of several excellent cultivars including 'Glenn' and 'Lippens'.
Florida continued to actively introduce, preserve, and improve cultivars from Asia, Africa, Central America, South America, the Caribbean, and the Pacific Islands. As a result of its commitment to mango research, Florida has become a center of secondary genetic diversity of mangoes, and cultivars bred in Florida have been introduced to many parts of the world and are still widely traded in markets around the world.
