Brussels-based organization Breeders Trust, which protects plant breeders’ rights, has conducted an online investigation revealing widespread violations in the sale of seed potatoes. Across various countries, closed Facebook groups and online marketplaces regularly offer table potatoes for use as seed potatoes, as well as small packages (1 to 2.5 kg) of seed potatoes that lack mandatory certification and official labeling. Corné van Beers, Director of Breeders Trust, notes that he also receives reports of bulk potato sales to farmers for use as seed material without permission from the breeder. In one court-mediated case, a potato farm owner was held liable despite not having sold a single kilogram — merely offering the potatoes for sale constituted a violation of breeders’ rights. Following pressure from Breeders Trust, several online advertisements have already been removed, though many farmers remain unaware of what is permitted.
The problem extends to e-commerce websites, where gardeners sell seed potatoes in small, uncertified bags. Breeders Trust purchased two 2.5 kg bags of seed potatoes (varieties Melody and Jelly) from a Dutch site; instead of a certificate, each bag contained only a handwritten note with the variety name and website address. The entrepreneur was summoned to court and ceased sales. Additionally, a processor recently rejected a potato delivery because the farmer could not prove legal use of seed potatoes — no invoice or royalty payment for Farm Saved Seed (FSS) of a protected variety was available. Mark Zuijdhof, Chairman of Breeders Trust, emphasizes that innovations in potato breeding depend entirely on respect for and enforcement of breeders’ rights. He warns that using illegal seed potatoes carries significant legal and phytosanitary risks for the entire supply chain. Breeders Trust will continue both enforcement and education efforts, making clear that illegal seed potato trade undermines the industry — especially during times of economic pressure when honest and transparent business practices are most needed.
