I think the Hatcher comes up in a post once or twice a year, so its been re-hashed a good bit, but anyways....
Here's a story for those of you who haven't seen me tell it already.........Cecil Broomfield, who owns Lawrence Zill's old place literally right across Hypoluxo from the Hatchers (who do a tremendous amount of business, congrats to them), has a Hatcher tree among the 3 dozen or so other varieties he has growing.....it is one of his worst selling and least requested mangoes at his stand.
Amazing what good marketing can do for a fruit!
Its a decent if unremarkable mango in terms of flavor.....its main attraction being its size, color, and flesh-to-seed ratio. I plan on planting one anyways though just to have it in the germplasm.
It was likely a Haden by Brooks cross....so making it a 'full sibling' of such mangoes as Sensation, Kent, and Fascell, the latter two of which it bears some physical resemblance to.
