DMR 401 is the next generation Downy Mildew resistant cucumber from Michael Mazourek’s breeding program at Cornell. Like DMR 264, DMR 401 has foliage that will resist Downy Mildew pressure at levels that kill any other standard slicing cucumber plant. DMR 401 is earlier and more productive than DMR 264. Fruits average 8 inches. Our 2015 trials of eight DMR cucumber lines from Cornell pointed to DMR 401 as the winner. Edmund contacted Michael Mazourek with the results, and he confirmed that DMR 401 also did the best in the Cornell trials. Grown at Sycamore Farm and Twin Oaks Seed Farm.
We are now selling our 2018 seed crop. Seed will be ready to ship on August 24th.
