The variety development program at WVAMK is one of the most critical components of our company.  To ensure that we stay ahead of the field in terms of variety development, WVAMK makes a definite effort to supply the South African potato grower with the best varieties possible.  Inputs are obtained from various sectors in the potato industry to ensure that we address the needs of our clients.  Every year between 15 - 20 new varieties are trialed within our own area.  Every variety is trialed for at least 2 years, after which culling takes place and the better varieties re-trialed for at least another two years.  Only after these varieties have proved themselves in term of yield, scab, resistance, resistance to other diseases, taste, processing ability, growth period or whatever other characteristic is needed by our customers, will they be distributed to there respective areas and re-trialed to ensure that we only supply varieties that conform with the needs of our clients.
