I am looking for Chestnut seed sources for a couple different types of crosses. If I have to get seedlings, I’m still interested, but I have to be very careful getting bare root because I’m not always in a position to plant large numbers immediately.

American chestnut (dentata) x Chinese chestnut (mollissima) where the mollissima parent is a good nut tree. Also would accept seedlings from a dentata x mollissima cultivar if they come from a good nut quality mollissima pollen cloud. Ideally, the mollissima would be hardy in zone five or colder since the trees will be raised in Wisconsin.

Seeds from a good North Italian Marrone type, perferably sativa rather than sativa x crenata crossed with a cold hardy mollissima parent. I don’t know a lot about the Marrone type and hardiness. What I do know is I have a number of friends who have been to Europe and really like roasted chestnuts from Northern Italy. Again, if there is a good cultivar of this type, I would be interested in seed nuts coming from a mollissima pollen cloud.
I am in Wisconsin. Blight is infrequent here, but I must respect the possibility. I have a couple 50 year old dentata on the property and a number of younger, bearing nut type Castanea trees of various and/or unknown sources. Most of what I am currently planting is Route 9 and Badgersett. I am familiar with cultivar Ace and I believe I have a 2025 source. Any leads on high quality sources for the above trees would be much appreciated.
