High-nutrition and disease-resistant purple and yellow-fleshed potato clones obtained
Date:4/24/2013

productivity in our latitudes, both in size and the number of tubers. Nevertheless, with the process of crossing and selection, the final clones having acceptable productivity has been achieved.

Nutritional value and resistant to pathogens

The four clones obtained are characterised by the high presence of antioxidants compounds, making them very attractive from a nutritional perspective. The three purple-flesh clones contain a large quantity of anthocyanins a highly appreciated pigment in the preparation of high added value foods , while the yellow flesh variety have carotenes essential chemical components for the diet and in greater quantities than in the usual commercial varieties.

Resistance to diseases is another of the achievements. The four clones show certain resistance to the pathogens analysed, such as the potato virus Y, as well as the Pectobacterium atrosepticum bacteria, which weaken the vegetable and considerably undermine its production.

Researcher Raquel Lpez highlights the importance of taking into account the clones achieved. "It is beneficial for European producers to have varieties of purple flesh potato that are adapted to the climatological conditions of this continent. Moreover, these varieties incorporate natural antioxidant compounds, which are nutritionally and visually attractive, both for restaurant professionals and for end consumers".
