These photos are of Dixie Red Delight in an orchard in Tanzania; the client suspected bitter pit. I don’t think it’s bitter pit, but maybe scab?

My Yellow Transparent tree has a Ashmead’s Kernel
branch that was covered with apples a month ago. They all turn yellow like this and fall off. Yellow transparent apples growing bigger and looking healthy on the same tree. I grafted Ashmead Kernel last year. Grew few feet. Is it dropping fruit because it’s a newish graft or is this some sort of disease or pest? I thought the fact that it’s a new graft wouldn’t matter since the tree is established.

Ashmead’ Kernel is a triploid so cross pollination is bit more complicated.

My own AK is a shy bearer, unfortunately, and it also drops a bit more than I’d like. I don’t think it’s a disease or pest problem here, and may not be for you, either. I suppose it could be an environmental (climate or soil) issue. It’s definitely not poor pollination here, as I have many nearby varieties which bloom at the same time. Your situation may be different.
That cracking in your photo looks like something I occasionally observe here in June on Cox’s Orange Pippin and the related Suntan, but not on AK. I’ve assumed it was scab-related, but I don’t see much evidence of scab on the leaves in your photo.

How maan diploid apples you have with bloom time overlapping your AK?
Fruit turning yellow and falling off usually is a sign of a pollination issue.
I have Yellow Transparent which started blooming earlier than AK but I think they did overlap for a short time. Not sure if Yellow Transparent blooms were in good shape by then. I also have Fuji but that didn’t have that many flowers this year. So I wouldn’t be too surprise if it’s a pollination issue. That would actually be a relief.
From what I understand, it would be better if you have two diploid apple varieties to help pollinate your triploid AK.
Hopefulky, next year your YT and Fuji will join force.
