The article presents the results of evaluation of rice varieties Flagman, Novator, Favorit, Olimp, Yubileyniy 85, Atlant, Kurazh, Rapan 2, Patriot, Azovsky, Polevik, Kazachok 4, Nautilus, Yakhont, bred in 1996-2019 by Russian breeders and grown in the Abinsky district, Krasnodar region by protein and amylose content in the grain due to the level of nitrogen nutrition during the growing season. The protein content in grain in all varieties with an increase in the applied nitrogen fertilizers from N90 to N120 increased by 0.03-0.56%. In 2016, the varieties Novator, Flagman, Olimp, Atlant, Kurazh, Kazachok 4 were 0.40% and higher; in the varieties Favorit, Polevik, Yubileiny 85, Patriot, Nautilus and Yakhont by 0.03-0.39%. The variety Patriot showed a slight growth trend in PC. In polished rice, PC decreased in two variants of the experiment to 78.991.9% PC, and the indicator was not dependent on the variant. Under the conditions of rice cultivation at N 120, a decrease in the amylose content in grain in varieties by 0.2-0.7% was observed. There was a general trend of a more significant decrease in AC in varieties in 2018. All varieties were assigned to the group of low amylose varieties with AC from 15.1 to 19.0%.
