Nadine seed potatoes are one of the most successful varieties, introduced around 1987 by famous potato breeder, Jack Dunnett. Nadine tubers are round in shape with a clean, white skin and cream coloured flesh. A high yielding seed potato variety, Nadine produces many tubers at the root and are a popular showbench variety. Nadine potatoes tend to be very popular at the supermarkets. Second earlies are typically ready for harvesting around 15-22 weeks from planting.
