Ok, I'm throwing in my 2 cents here. Currently I'm growing America, Buffalo, and Concord. Next spring I'm planting more America, Sherdan, and Cab Franc. I've been researching the various varieties that will grow in Ohio, Zone 6A (similar to your location in Illinois). I've put together a cheat sheet (below) that I've been making. Based on research that I've done and discussions here on the forum, I'll planting Cab Franc Spring of 2019 and Marquette in Spring of 2020. I'm also interested in growing Petite Pearl. If I listed grafted, I plan on using the 101-14 rootstock. Here's the data:
America red 4 early season TWC resistant
DeChaunac red 5 mid-season TWC Mostly resistant
Dornfelder (grafted) rose 6 early season VSP susceptible
Frontenac red/rose 3 late season TWC somewhat resistant
Geneva Red red 4 mid-season TWC susceptible
Leon Millot red 4 early season TWC Botrytis prone
Marechal Foch (grafted) red 5 mid-season TWC mostly resistant
Marquette red 3 early season TWC resistant
Petite Pearl red 4 late season TWC highly resistant
Sabrevios rose 3 early season TWC resistant
