Spirit of '76 (mango)

The original tree was grown on the property of Laurence Zill of Boynton Beach, Florida and was reportedly a seedling of the Zill cultivar that had been open cross pollinated with Haden.

A 2005 pedigree analysis estimated that Spirit of '76 was indeed a Haden × Zill cross.

Though Spirit of '76 did not gain commercial acceptance due to its soft flesh, it has been propagated as nursery stock and sold on a limited basis as a dooryard tree for home growers in Florida.

Spirit of '76 trees are planted in the collections of the USDA's germplasm repository in Miami, Florida,[1] and the Miami-Dade Fruit and Spice Park in Homestead, Florida.

It is completely fiberless with a rich, aromatic flavor, and contains a monoembryonic seed.
