Pollen-sterile chestnut cultivars: can someone answer this?

13 years ago

I'm placing an order for hybrid chestnut seed to grow my own next spring, and one of the varieties I'm looking at is Colossal. Burnt Ridge Nursery lists the grafted saplings of this variety they sell as pollen-sterile and suggest planting another variety or two to get proper pollination.

My question is, does the same hold true for seedlings of the parent trees? Since they're offspring of an already hybrid tree, and they must have been pollinated by another variety as well to set nuts, would a planting of just Colossal seedlings be able to pollinate each other since they'd have such a wide mix of genetics in there?

Thanks!
