I have a semi-dwarf nectarine tree that I planted about 10 or 12 years ago that has never produced any nectarines. Every year the tree sets a good amount of fruit but the fruit never makes it to fruition. I have yet to have any of the fruit get to be the size of a golf ball. By the time the fruit has been on the tree for a few weeks they all start to rot and fall off. I have 8 peach trees (three different varieties) that produce very well. Since a nectarine is simply a peach without any fuzz I can't figure out why the peaches produce but the nectarine doesn't.
