STUDY OF PROMISING POTATO GENOTYPES WITH A HIGH CONTENT OF ANTIOXIDANTS IN VITRO

In the modern world, potatoes remain a consistently valuable culture for humans. It primarily serves as a component of good nutrition due to the high content of carbohydrates in tubers. It is a raw material for producing alcohol, starch, protein, and other products used in various areas of the national economy. Scientists currently pay attention to potatoes with colored tubers, as they contain many antioxidants. These secondary metabolites help people cope with cardiovascular diseases, diabetes, overweight, cancer, hypertension, and other diseases. Therefore, creating new forms of potatoes with colored tubers is one of the primary tasks of potato farming. The article studied 16 potato samples with a high content of anthocyanins and carotenoids. We conducted the studies at the Department of Biotechnology of Russian State Agrarian University - Moscow Timiryazev Agricultural Academy and in the field trial of the All-Russian Research Institute of Phytopathology (Bolshie Vyazemy, Odintsovo district, Moscow region, Russia). We used biotechnological introduction methods into in vitro cultivar, reproduction, and chemical treatment during the study. As a result of this work, among the studied samples, we identified No. 3 and No. 5 with an increased starch content of 18.53% and 19.08%, respectively. In vitro cultivar showed that samples with red flesh had a higher growth rate and development, while samples with blue flesh significantly lagged in these terms.
