Among the 10 nominees is LoveMySalad.com, described by its developer, seed breeder Rijk Zwaan, as a "social salad network" featuring blogs, news, recipes and preparation tips, employing a range of social media.
Marketing manager Auke Ferwerda said: "We were already planning to highlight LoveMySalad.com on our stand and the nomination provides a welcome boost."
Three vegetable varieties are also nominated, two with British connections. Purple sprouting broccoli, the result of a joint breeding programme between Bejo Zaden and Elsoms Seeds, is well established in the UK market and is now grown organically in the Netherlands.
Syngenta has been nominated for its Angello seedless snacking pepper, which was bred at Melrow Salads of Merseyside for Marks & Spencer. The Sungreen tomato from Japan's Tokita Seed is also nominated.
