Qinghai Seed-Potato and Starch Value Chain
Virus-free plantlets, minitubers and successive seed generations pass through tissue culture, staged multiplication, field isolation and virus monitoring before contract growing, harvest, cleaning, weighing and storage. Table and seed potatoes serve cooperatives and growers; processing tubers are washed, rasped, separated, refined and dried into starch, with protein, fibre and fertiliser inputs going to food, catering, feed and farm-supply buyers.
