The First Line of Defense for Seed Potatoes

Combining apical meristem virus-free technology with a Class 100,000 sterile laboratory, each virus-free seedling is protected from viral infection at the genetic level, forming the cornerstone of Junsheng’s seed potato system.

  • Apical Meristem Isolation and Virus Elimination — Cut a 0.2–0.3 mm section of the apical meristem to effectively eliminate major viruses such as PVX and PVY.
  • Class 100,000 cleanroom environment — Maintains positive pressure throughout the entire process to prevent cross-contamination and ensure the purity of the 100% parent strain.
  • PCR Molecular Testing — Molecular testing is completed for each batch before it leaves the nursery, and a certificate of quarantine compliance is issued.
  • High-efficiency rapid propagation capability — Meet the massive seed demand of farmers and processing companies placing large-scale orders.

Substrate Propagation · High-Vitality Seed Sources
Smart, Controlled Pest-Resistant Greenhouse

Sterile seedlings are transplanted into high-standard smart greenhouses, where they are cultivated entirely using standardized growing media to produce highly vigorous, disease-resistant microtubers weighing 2–10 g each, with a round and plump shape.

Exclusive Breeding Base at High Altitude

We have selected a high-altitude, isolated area at 41° north latitude—a cool region free from soil-borne diseases—to establish our company’s exclusive, proprietary open-field propagation base. We implement a unified, standardized “100%” cultivation system alongside a rigorous plant protection and weed control regimen to ensure absolute autonomy and control over the quality of our seed stock.
