Helping You Beat CGMMV - Grow Smarter with CGMMV Resistant Cucumbers
Cucumber Green Mottle Mosaic Virus (CGMMV) remains one of the most serious disease threats in commercial cucumber production. The contact-transmitted virus spreads easily via tools, hands, water, rodents, and even pests, creating the potential for rapid, devastating crop loss.
That’s why BASF's vegetable seeds business, operating in the market under the Nunhems® brand, focused its fresh cucumber breeding and technical services on helping growers minimize this risk through CGMMV-resistant varieties and integrated crop management support.
“In high-wire systems, CGMMV can derail months of investment in pruning, lowering, and crop management,” according to Robert Swinkels, high tech cucumber breeder at BASF | Nunhems. “Resistant varieties give growers a critical layer of protection against this risk.”
CGMMV infection causes stunting, fruit blemishes, and yield losses often exceeding 30% to 40% in heavily potentially infected greenhouses, says Swinkels. The economic impact can potentially reach over $100,000 per acre per season, especially in long-cycle or high-wire crops where replanting isn’t feasible, according to Swinkels.
All New Cucumber Varieties Now Come Standard with CGMMV Resistance
BASF | Nunhems began its CGMMV resistance breeding program in response to grower demand, with resistant varieties entering the market in the following years.
“Resistance is only valuable if it comes with the yield potential, fruit quality, and plant vigor growers need,” said Swinkels. The BASF | Nunhems breeding team continues to close the gap between resistant and susceptible varieties to minimize production trade-offs.
All in all, we offer several CGMMV resistant cucumber varieties in the US & Canada, including:
- Long English: DUnavin, SEquence, SEpire, SEiber, Hi Lumiere
- Mini Cucumber: Beebond (NEW!), Beemaze (NEW!), Beefresh (NEW!)
