영문 초록

Potatoes have been recognized for a long time as one of the major food crops as well as horticultural crops. Potato production as a table food has been decreased in developed countries, while it has been steadily increased in the third world countries for it importance as food source. It is a new trend to look for the food, not only as a feeding crop but also healthy food. It is also time for the potato producers to look for the potato having high economic value as found in medicinal plants. There are great diversities in potato species, indicating that valuable compounds can be found in different amounts, depending on potato species. We screened the cultivars, breeding clones, and germplasms based on the vitamin C, Vitamin E, antioxidant compounds, diverse sugar types, important amino acids, and other valuable compounds. We could select the breeding clones KC003, 98Wl17, 99j717, and Vally 8 (A group) due to their high levels of antioxidant compounds, and it can be said that most of the red and purple colored potato clones belong to the A group. In the contents of essential amino acids, ‘Taebook Valley’,‘Summer Valley’ and other breeding clones were found to be high in amount. We also made crosses between breeding clones with high biological function and low agronomic traits and low biological function with high quality in agronomic characteristics . The patterns of genetic trends of these offsprings in comparison with their parents will be reported as well. And the potential of using potato as antibody production of anti-cancer will be discussed.
