Each year, the most promising clones are selected and retained for further multiplication based on a number of criteria from size, shape, yield, disease resistances, storage and cooking qualities and tubers are sent to a number of trial sites both throughout the UK and overseas.
From the second year onwards clones are trialled at Cygnet PB’s site in Cambridgeshire in the heart of the UK’s main potato growing regions, where detailed information about the individual clones is collected. The breeding programme has a strong focus towards selecting clones that will suit the potato processing industries in domestic as well as overseas markets.
Overseas trials in the more arid regions of Spain test the clones for tolerance to heat and drought stresses. Trials with a number of external organisations provide further, independent data on agronomic features, disease and pest resistance.
