Another one to add to this list is Kesar. It sets fruits in clusters and retains most of them. The only problem is that you need to thin the fruits so that the fruit gets big. The fruits I got last year were outstanding . This year, the mangoes are smaller, but I have more than 100 on the tree, without any spraying.
My Edgar, topworked last year on a Glenn, is holding on to 5 fruits on two branches. On the other hand, my Angie, which flowered sparsely this year, has no fruit on it. My Mahachanok and Sweet Tart , which are both over seven feet in height and look really healthy, did not even flower.
