From tissue-cultured plants to field-ready G3 seed — SPSG supplies authorised, traceable potato seed to farmers across the region.
Siwan Potato Seed Grower has spent decades working the soil of Kaithal district, building direct relationships with CPRI and PTC for authorised source material and passing that discipline through every generation of seed we multiply.
What began as a single family's seed plot is now a trusted supply point for farmers who need seed they can rely on — correctly labelled, correctly stored, and correctly graded, season after season.
Every seed lot moves through a disciplined multiplication chain before it reaches a farmer's field.
Disease-indexed plantlets raised under controlled lab conditions — the clean starting point of every seed line.
Foundation-grade seed sourced through CPRI and PTC-authorised channels, forming the base of our multiplication chain.
Net-house grown minitubers, the bridge between tissue culture and open-field multiplication.
First field-multiplied generation from foundation stock — highest purity available for farm planting.
Second-year multiplication, cold-stored and graded — our most widely supplied seed class.
Farmer-grade planting seed, priced for volume cultivation while holding to the same traceability standard.
