Ok, I got the low down on this mango. It was, as we pretty much determined, part of Gary Zill's breeding program. It is a Julie x Gary cross. Gary no longer has this tree as part of his collection. He eliminated the tree due to its smaller fruit size and poor production, worse than the Gary mango. Due to these facts, there was nothing positive enough that ge felt made it worthwhile keeping. The only trees that are around would be those at tge USDA and possibly part of the Fairchild Collection if Richard Campbell planted one out.
