The organic potato sector has been given a much-needed boost after a breakthrough by UK scientists.

Researchers at Newcastle University’s Nafferton Ecological Farming Group have discovered a new range of 10 potatoes varieties resistant to late light blight.

The news means the potatoes can be produced without the assistance of copper oxychloride sprays to fight the problems with blight.

The group also worked with 13 partner nations across Europe to develop specialised composts to help speed the growth of the plants.

The organic sector has consistently struggled to produce potatoes in a cost effective manner, with organic potatoes retailing for twice the price of the standard offer. Producers are now hoping the development could provide a welcome boost to the category.

The new range of potatoes includes completely new varieties, some of which have been named Eve Balfour and Lady Balfour, while others, Sarpo Mira, Sarpo Axonia and Sarpo Tominia were developed more than 40 years ago in Hungary before being rediscovered.
