Frank Mulcahy explains during his interview with ABC Radio - Tasmanian Country Hour, that the parameters under which the varieties were chosen in the 1980s may be different to the parameters under which they are chosen now.

This Hort Innovation report covers the efforts made to maintain a large bank of different potato varieties, and what they are good for. Specific focus was made on viral resistance, disease resistance, specific gravity and various cooking factors. Potatoes from Europe to America are included in this potato bank.

This Hort Innovation report explores the genetics behind breeding new varieties of potatoes. The report looks into developing genetic analysis tools to improve cultivar selection and development. With a focus on improving resistance to potato cyst nematodes and potato virus Y this 2012 paper provides great insight into how new cultivars are chosen.

Between 1995-2001 specific gravity of potatoes from Koo Wee Rup declined substantially. Possible causes of specific gravity loss were explored in this report. Cultivars, crop production management and climate conditions were all investigated.
