From the upper left and in clockwise order, the cultivars are: ‘Kent’, ‘Beverly’, ‘Alphonso’, ‘Carrie’, ‘Palmer’, ‘Valencia Pride’, and ‘Keitt’. The one in the middle is ‘Tommy Atkins’. Additional photographs of mango cultivars are available from Wikimedia Commons, including comparative photographs of some of today’s cultivars (and others) with ‘Ataulfo’, a mango commonly sold in local supermarkets. Given my enjoyment of the mangoes available to me and suspecting that locally-ripened ones might taste even better, it’s an ardent desire of mine to one day attend the Fairchild Tropical Botanical Garden‘s annual Mango Festival and sample, sample, sample. Unfortunately, no trip planned for me to this year’s festival on July 9-10.
Mangoes have been in cultivation for millenia, with India being the world’s largest producer (but Pakistan the largest exporter). Along with the article, Wikipedia provides an excellent set of resources for additional reading.
