Abstract
There has been given an analysis of the use of rice varietal mixtures in production compared to one variety crops. Since the productivity of most varieties has reached its biological potential, it is necessary to develop new methods and approaches to improve productivity. Nowadays the rice varieties Rapan 2, Polevik, Patriot, Nautilus, and Apollon occupy the main production areas. In accordance with the instructions of the Russian Minister of Agriculture, rice production in Russia must increase to 2 million tons by 2030. In this regard, the purpose of the current study was to find new ways to increase crop productivity, including the acceleration of the breeding process using DNA technologies and the use of variety mixtures in production. There were conducted lysimeter, greenhouse, and production trials in 2023-2024. Production trials of rice varietal mixtures have shown their advantage in productivity and blast and lodging resistance compared to one variety crops. Productivity increase of the varietal mixtures compared to one variety crops ranged from 3.6 to 13.9 hwt/ha. The varietal mixture Apollon+VNIIR7442 has demonstrated the largest productivity at LLC “P.P. Lukyanenko Agricultural Enterprise”, with 82.2 hwt/ha, exceeding the yields of individual rice varieties by 10.2 hwt/ha.
