Sweet Tart was a seedling of Zill Indochinese (ZINC) from the breeding project of Gary Zill in Boynton Beach, FL. Its original planting number was C-1.
The fruit are small, yellow at maturity, with an oval-oblong shape similar to ‘Glenn’. The flesh is medium-firm, fiberless, and orange in color, containing a polyembryonic seed with poor flesh-to-seed ratio. The flavor is nothing short of amazing, a flavor bomb with intense richness and complexity, its strong tart component like that of a candy that gets balanced out by a big punch of sweetness. As the fruit becomes more ripe, its tart component diminishes as the sweetness becomes cola syrup-like.
The trees are vigorous growers with somewhat vertical growth habit. They have very good anthracnose resistance both at the floral and fruiting stage. Unfortunately, Sweet Tart trees seem to have trouble achieving full blooms, and have particularly struggled to flower as young trees during mild winters. Where they do flower, they set fruit extremely well and may even require thinning to achieve improved fruit size.
Fruit splitting can also be a problem for Sweet Tart particularly those grown in the interior, and some issues with uneven ripening have been observed.
We are evaluating Sweet Tart for its resistance to bacterial spot and rot, as well as its ability to fruit in future seasons. At this point we feel it may be resistant to bacterial spot, but somewhat prone to rot due to fruit clustering and the minor splits it can develop.
It is a mid-season mango ripening from July to August.
