Short vegetation period and resistance to potato cyst nematodes are just the beginning of Zeta’s advantages.


Variety characteristic:

Zeta is a plant of medium height with a compact canopy. The length of the growing period is approximately 96 days. It reaches technological maturity the end of August what makes Zeta an ideal variety for an early delivery at campaign start in the processing companies. The undoubted advantage of the variety is its outstanding resistance to potato cyst nematode Globodera pallida (Pa3), the occurrence of which pathogene has increased in recent years in Poland and the Western Europe. Under favorable conditions, it can achieve a starch content of over 20% and a total yield of over 40 t/ha.
