So-called "graft hybrids" do happen, but they are rare. One that is reasonably well verified is "Pyronia veitchii" which is a graft hybrid of Pyrus and Cydonia, supposedly having arisen as a shoot from the graft union of pear and quuince. The plant is indeed a mix of both species. |
This is a very rare situation, though, so it's unlikely the seed grafting would work much of the time. As you say, though, it's pretty hard to verify it when it's between two very similar individuals. You would almost have to have "marker" traits in each seedling to verify the "hybrid". Something like dark red shoots in one and green in the other, with the hybrid having light red shoots.
