If they are the actual Dunstan variety grafted from the original tree they will not pollinate each other. If they are Dunstan brand trees started from seed at Chestnut Hill, they will. I'm assuming that walmart is selling the later. This is equivalent those of us who are buying chestnuts from Dunstan trees from Chestnut ridge and growing seedlings from them. Any chestnut grown from seed is genetically unique and not genetically precluded from pollinating other chestnuts. If you take any chestnut, take clones from it, and graft them to other seedlings. Those seedlings will be genetically identical and can't pollinate each other.
O hope I made that more clear not less clear. Most other varieties of chestnut are true varieties clonally propagated. Dunstan is unique in that it was originally a variety but is also a trade name. Also, I believe genetic incompatibility is not the only thing that can preclude pollination. I believe there can also be timing issues with some varieties. I'm only working with Dunstan and Chinese from nuts, so I'm not fresh on the topic. I'm trying to remember from some of the digging I did before I started with chestnuts. I believe I recall seeing a variety pollination chart for some varieties like apples.
Thanks,
Jack
