Rice is one of the most important grain crops. Primorsky krai is the main region of rice cultivation in the Russian Far East. Its soil and climatic conditions limit the time for the growth of rice plants. For this reason, all breeding programs in this region are aimed at creating new high-yielding and early maturing varieties with high technological properties of cereal and resistance to diseases. The research was conducted at the Primorskaya Scientific Research Experimental Station of Rice (a branch of Federal Scientific Center of Agricultural Biotechnology of the Far East named after A. K. Chaika) in the Spassky District of Primorsky Krai in 2019–2021. There were 10 breeding lines in the study. During the study period, rice lines were assessed to identify the best features in terms of productivity elements and technological properties of grain. As the result, new promising breeding material was discovered. This material has a high potential for the productivity and technological properties of rice grain.
