Scientific research to determine the optimal combination of technical means in the system of cleaning and sorting seeds. We carried out a system analysis of the current state of technical means of cleaning and sorting. The main task of promising research and development work is the development of a high-precision computer-based seed sorter with an electron-optical analyzer of their properties, including the internal structure of seeds. The main result of the use of a complex of technical means of electron-optical cleaning and sorting of seeds in the selection and seed production of grain crops is an increase in their yield.
