Worldwide, hundreds of mango cultivars exist. In mango orchards, multiple cultivars are often grown together to improve cross-pollination. Two of the most important cultivars are the Chaunsa, which is particularly common in Pakistan, and the Tommy Atkins, which dominates the world export trade because it can be easily transported and has a good shelf-life, although it is reputed not to have the same flavor as that of a chaunsa.
