Cultivars
There are many hundreds of named mango cultivars. In mango orchards, several cultivars are often grown to improve pollination. Many desired cultivars are monoembryonic and must be propagated by grafting, or they do not breed true. A common monoembryonic cultivar is 'Alphonso', an important export product, considered "the king of mangoes."Cultivars that excel in one climate may fail elsewhere. For example, Indian cultivars such as 'Julie,' a prolific cultivar in Jamaica, require annual fungicide treatments to escape the lethal fungal disease anthracnose in Florida. Asian mangoes are resistant to anthracnose.The current world market is dominated by the cultivar 'Tommy Atkins', a seedling of 'Haden' that first fruited in 1940 in southern Florida and was initially rejected commercially by Florida researchers. Growers and importers worldwide have embraced the cultivar for its excellent productivity and disease resistance, shelf life, transportability, size, and appealing color. Although the Tommy Atkins cultivar is commercially successful, other cultivars may be preferred by consumers for eating pleasure, such as Alphonso.Generally, ripe mangoes have an orange-yellow or reddish peel and are juicy for eating, while exported fruit are often picked while underripe with green peels. Although producing ethylene while ripening, unripened exported mangoes do not have the same juiciness or flavor as fresh fruit.Phytochemistry
Numerous phytochemicals are present in mango peel and pulp, such as the triterpene lupeol. Mango peel pigments under study include carotenoids, such as the provitamin A compound, beta-carotene, lutein and alpha-carotene, and polyphenols, such as quercetin, kaempferol, gallic acid, caffeic acid, catechins and tannins. Mango contains a unique xanthonoid called mangiferin.Phytochemical and nutrient content appears to vary across mango cultivars. Up to 25 different carotenoids have been isolated from mango pulp, the densest of which was beta-carotene, which accounts for the yellow-orange pigmentation of most mango cultivars. Mango leaves also have significant polyphenol content, including xanthonoids, mangiferin and gallic acid.
