If I plant two apple tree seedlings from the same plant, will the offspring be different enough to pollinate?

Question

Actually I have Pawpaw seeds that could be of the same plant, but Pawpaws are similar to apples in that they need two different types of plants to cross pollinate.

Answer 1

Some apples, yes, but Pawpaws are self-incompatible, requiring cross pollination from another unrelated pawpaw tree.

If you try to germinate the seeds, you should refrigerate them with some moist sphagnum moss for 90 to 120 days at 32° to 40° F before germination.

Answer 2

yes, but Pawpaws are self-incompatible, requiring cross pollination from another unrelated pawpaw tree.

so. . . that guy is right
