Apple Mosaic Virus: Keep or discard tree?

[danchappell]

Here is a related thread.

The infected tree stopped showing symptoms and is doing great now that the weather has warmed up. I plan to keep mine.

What is this yellow mottling on apple leaves?

One of my apple trees has this yellow mottling on the leaves. The tree is Granny Smith on M111. It also has a grafted Gordon limb that shows identical symptoms. The Fuji tree six feet away has normal leaves. Is this cedar apple rust or something else? I have looked at pictures on the net but don’t see any that seem to exactly match.
