ዩኬ የመጀመሪያውን በቅድመ-የተመረተ የድንች ዝርያ ፓይፐርፕላስ አብሮገነብ የበሽታ መቋቋምን አፀደቀች
ቁልፍ ማውጫዎች
- First UK precision-bred potato approved by DEFRA
- Maris Piper derivative with three resistances
- Late blight, PVY and PLRV covered
- Resistance genes taken from wild relatives
- Still needs Food Standards Agency approval
ለምን አስፈላጊ ነው
- ለገበሬዎች
- Fifteen fungicide passes a season is the cost base this variety is designed to remove.
- ለአቅራቢዎች
- Virus resistance could move seed production from Scotland into England, cutting transport and emissions.
- ለባለሀብቶች
- Approval is not market entry: FSA clearance, National Listing and seed multiplication mean at least five years.

The UK has granted regulatory approval to its first precision-bred potato variety: PiperPlus, a Maris Piper derivative with innate resistance to late blight (Phytophthora infestans), Potato Virus Y and Potato Leafroll Virus. It was developed by Professor Jonathan Jones and his team at The Sainsbury Laboratory over decades of research into plant immune genes, and confirmed by DEFRA after scientific evaluation by the Advisory Committee on Releases to the Environment. Under the Genetic Technology (Precision Breeding) Act 2023 it qualifies as precision-bred because the modifications could have arisen naturally or by conventional breeding: resistance genes from wild relatives encode immune receptors that detect pathogens and trigger the plant’s own defences. British growers typically apply preventative fungicides up to 15 times a season; reducing that would cut costs, tractor passes, emissions and soil compaction. Virus resistance also matters for seed production, since viral load accumulates over generations.
The United Kingdom has granted regulatory approval for its first precision-bred potato variety, bringing the disease-resistant Maris Piper-derived cultivar PiperPlus closer to commercial production. Developed by Professor Jonathan Jones and his team at The Sainsbury Laboratory (TSL), PiperPlus possesses innate resistance to late blight (Phytophthora infestans), Potato Virus Y (PVY), and Potato Leafroll Virus (PLRV)—three of the most devastating threats to potato cultivation. The approval follows decades of research into plant immune genes and was confirmed by the UK’s Department for Environment, Food and Rural Affairs (DEFRA) after scientific evaluation by the Advisory Committee on Releases to the Environment. Under the Genetic Technology (Precision Breeding) Act 2023, the variety qualifies as precision-bred because its genetic modifications could have occurred naturally or through conventional breeding. Rather than relying solely on chemical crop protection, researchers strengthened the natural immune system of the Maris Piper by incorporating resistance genes from its wild relatives, which encode immune receptors that detect pathogens and activate the plant’s innate defenses.
