An important criterion in assessing varieties and hybrids of sugar beet is their ability to long-term storage. Therefore, the selection of sugar beet hybrids, which have good keeping quality, is becoming one of the pressing issues of the sugar beet industry. Changes in the quality indicators of root mass during storage were monitored after 30 and 60 days according to the generally accepted method, which provides for laying mesh samples. As a result, it was found that in the root mass of hybrids of normal type the content of α-amino nitrogen increased after 60 days of storage by 2.5-2.9 times compared with the initial state, hybrids of normal yielding type - by 2.7-3.0 times , normal sugar type - 3.3 times, and sugar type - more than 4 times. The accumulation of sodium in root mass in all hybrids occurred approximately equally. For three years of research, after 60 days of storage, the most sodium was found in root mass of the normal compact and Hercules hybrids, and least of all - in the root mass of sugar type.
