The production and sales division of Averis Seeds is founded in 2001 after the merger of the seed potato sales division of AVEBE and the starch potato division of HZPC. The division production and sales is seated in Foxhol. The majority in the list of the ten largest starch varieties in Europe are sold by Averis Seeds, indicating that Averis Seeds is the authoritative seed producing company of starch varieties in Europe.
The primary objective of Averis Seeds is to provide enough material to the Dutch potato starch industry. Besides the Dutch market Averis Seeds produces also seed potatoes for the potato starch industry in other parts of Europe. The seed potatoes are produced on the clay soils in the northern part of Groningen and in the Noord-Oost Polder and on the sandy soils in the provinces Drenthe, Gelderland and Overijssel. Strict selection criteria are used to select the best seed potato producers to grow the KARNA varieties and the varieties given under license. The high quality seed potatoes are evaluated and certified according to the standards of the NAK (the Dutch General Inspection Service for Agricultural Seed and Seed Potatoes).
Most of the seed potatoes sold by Averis Seeds is classified as E or A. Subsequently the starch potato growers will multiply these seed potatoes one or two years themselves under the so called TBM regulation. Based on these conditions it is possible for starch potato growers to multiply their seed potatoes strictly for their own use on soil infested with the potato cyst nematodes. The seed potatoes produced with the TBM system are evaluated according to the NAK protocol but not certified.
The trade of certified seed potatoes is increasingly based on contracts for one or two years on the delivery of seed potatoes with a C-classification. This material is evaluated and certified by the NAK and used by starch potato growers for direct delivery to the starch potato industry.
The moment of delivery of the seed potatoes to the customer is often depending to their classification. The seed potatoes with the classification E and A are mostly delivered in the autumn, the classification C seed potatoes are often delivered in the spring.
Besides the delivery in 50 kg bags, the seed potatoes are delivered in big bags.
