New varieties of disease-resistant cucurbits are commercially available as a result of Cornell University's Eastern Sustainable Organic Cucurbit Project.
Through participatory efforts with farmers and regional seed companies, Extension researchers developed new varieties with organic producers in mind, focusing on resistance to common diseases and pests, but also on production and culinary characteristics important to organic farmers.
“All of our successes with DMR are owed to farmer input,” says project director Michael Mazourek. “We took moderately resistant material that we had at Cornell, moderately resistant material identified by organic farmers, and people are seeing the literal cross-pollination of these partnerships in DMR varieties now available to growers.”
‘Trifecta’ muskmelon stood out for its excellent eating quality and yield–even under levels of downy mildew pressure that defoliated most commercial melon varieties. The variety also exhibited good bacterial wilt resistance and was less prone to damage from striped cucumber beetles. ‘Trifecta’ is currently available for sale through Common Wealth Seed Growers and Southern Exposure Seed Exchange.
DMR401 cucumber, a downy-mildew resistant (DMR) slicing cucumber variety, now available for purchase through Common Wealth Seed Growers, High Mowing Organic Seeds, SeedWise, and Southern Exposure Seed Exchange.
DMR264 cucumber, excellent resistance to new strain of downy mildew, smaller and bred for warmer climates with severe pressure from downy mildew. Available from Common Wealth Seed Growers.
Additional varieties are being tested for release.
The Eastern Sustainable Organic Cucurbit Project has received funding from the USDA Organic Research and Extension Initiative, as well as the Organic Farming Research Foundation, Sustainable Agriculture Research and Education (SARE), and the Clif Bar Family Foundation.
