The potato will be not only a basic food item as well as one of the main food crops worldwide, the idea contains a huge variety of minerals as well as phytochemicals with potentially health-promoting effects. Greater awareness about the importance of consuming these phytochemicals (substances in which help to protect cells against the harm caused by carcinogenic processes) as well as the growing interest inside the development of completely new products with specific organoleptic properties, have led to the appearance of different initiatives to genetically enhance the potato. Clones have been identified that has a soft consistency, total disintegration when boiled, low humidity as well as high “flouriness” as well as which can be used for preparing mashed or roast potatoes.


completely new varieties that has a high pigment content have been developed recently. They are therapeutically very effective, above all in terms of antioxidant activity, as well as have a dual function: firstly, they are beneficial for health, as well as secondly, these pigments provide a deep purple or red colour, which makes them very attractive for the consumer; This specific offers completely new opportunities with respect to marketing as well as functional foods.

Among the compounds most studied by the perspective of genetic enhancement are, firstly, chlorogenic acid, owing to its implications for human health as well as its functions in defending the plant against pathogens, as well as secondly, the group of carotenoids. Apart by being associated that has a deep yellow colour, some of the majority carotenoids inside the potato are considered to be of prime importance for eye health as well as in lowering the risk of developing age-related macular degeneration.

The concentration, distribution as well as composition relating to each of the compounds inside the potato are also heavily influenced by environmental factors, such as crop management, climate, soil, incidence of pests as well as diseases, harvesting time, mechanical damage, storage time as well as conditions.

The research in which NEIKER-Tecnalia has been conducting since 2014 aims to obtain varieties with high levels of bioactive compounds in which benefit health (anthocyanins, phenols as well as total carotenoids), an antioxidant capacity, as well as adapted to the growing conditions of our area. To do This specific, an assessment was begun on a series of red as well as purple flesh varieties with low adaptation as well as yield, so crossbreeding was commenced in order to obtain optimum varieties in terms of yield as well as nutrition as well as marketing.

Set to take place throughout This specific year are comparative agronomic trials as well as the multiplication of the most promising clones in which will shortly make up completely new varieties to be developed as well as marketed in due course.

NEIKER highlights the importance of having clones like the ones obtained. “For producers the idea will be interesting to have purple potato varieties in which adapt to a broad range of climate conditions. These materials also contain natural antioxidant compounds, which are attractive by the nutritional as well as visual point of view for professionals inside the planet of catering as well as also for end consumers.”
