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 to not have the same flavor as that of a chaunsa.
The International Mango Festival, held annually in Delhi, India during early summer, is a two-day festival showcasing mangoes. It has been held since 1987. More than 550 varieties and cultivars of mango are featured in the festival for visitors to view and taste. Among these are alphonso, mallika, amrapali, himsagar, malda, balia, chorasya, dhaman, dhoon, fazia, gelchia, nigarin kheria, ruchika and shamasi.
