This mango was a chance seedling selected by the Zill family in Boynton Beach, FL decades ago and has been speculated to be a cross between Palmer and Tommy Atkins.
A USDA pedigree analysis estimated Keitt as a likely parent, to whom it bears no resemblance. Regardless of parentage though, Zillate was propagated to some degree by the Zill nursery but discontinued due to uneven ripening issues.
The fruit are medium-to-large, oblong in shape and develop a deep purple color long before reaching maturity, much like Palmer. They turn red with yellow background color as they begin to ripen.
The flesh is yellow, firm, with minimal fiber and contains a monoembryonic seed. The flavor is quite good, particularly for a late season mango. It belongs in the classic flavor group and has notes of dried stone fruit with honeyed sweetness. As mentioned, the flesh can sometimes ripen unevenly, though this hasn’t been a major issue with ours.
The fruit has good anthracnose resistance but is highly susceptible to mango bacterial black spot and rot fungi, to such a degree that we finally decided to begin topworking the tree after the 2019 season.
The trees have a spreading growth habit with open canopy and long internodes. Ours is considerably wider than it is tall. They are moderately vigorous growers, and can be heavy producers.
Zillate ripens from late July through August.
