The Institute of Potato Growing of the National Academy of Agrarian Sciences of Ukraine has developed two new potato varieties, "Solokha" and "Khortytsya," which are rich in vitamin C and are said to boost the immune system. These potatoes have unusual colors, blue-purple and red, due to the use of genes from wild potato species resistant to pests and diseases. The institute has a genetic potato collection with 3016 different specimens. The new varieties were created using classical selection methods and not genetic modification.
