Hazel Nut pollination and Incompatibility Alleles

Did some reading of the resource material at Rutgers.  Did some checking on what to plant in my small orchard.
Try to avoid the same Allele numbers if planting only two.

Allele self-incompatibility
Somerset  3 and 10 (3 expressed in Pollen)

York 2 and 21 (only 21 is expressed in pollen)

Hunterdon 1 and 3 (3 expressed in Pollen)

Raritan 3 and 22 (3 expressed in Pollen)
Grand Traverse (S11S25) - It has S-alleles 11 and 25 with both expressed in the pollen, and blooms in mid-season in New Jersey. It is compatible in both directions with all of the cultivars listed above.
McDonald 2 and 15 (15 expressed in pollen)

Wepster 1 and 2 ( 1 expressed in pollen)
McDonald and Wepster are compatible.

 

Interesting! I have western/beaked hazelnut growing like a weed. But it's wild, low production, and I compete with the squirrels and jays.

I never considered cultivars more suited to serious production. I'm curious. What led you down this path?

After seeing all my Kiwi die off this year I wanted to replace them with something more suitable for North Alabama. Last year I planted Wepster and Mcdonald along with a one found locally. This year I did some looking around and found out about the research done at Rutgers and the varieties they released in 2020.  There are some suggestions on how to create a larger commercial type operation.

This is off-topic, but it was interesting reading down that list of varieties because... 20 years ago, when I lived in New Jersey for a few years, I lived in Somerset County in the Raritan River drainage basin, and just 2000 feet from the Hunterdon County line. It makes me wonder if that's thick hazel country and I was just entirely unaware.
