To obtain homogeneous genetic seed of sunflower parent components, which by varietal and sowing qualities, must have a varietal purity of 99.6-99.9%, it is necessary to ensure their precise (exact) separation according to the morphological and physico-mechanical properties in the complex. Based on the necessary requirements for the technological processes of cleaning and separation of seed mixture, a rational precision technological line has been developed for the processes of separation of seed material of sunflower, which includes automation of technical equipment. Also, to increase the efficiency of the sunflower breeding process, a device for automatic phenotyping of seeds has been added to the developed production line, which makes it possible to significantly intensify and reduce the selection process and improve the design of the crossing program due to bioinformative data analysis and sorting of seeds. As a result of the analysis of technological methods for the separation of sunflower seed material and their technical support, it has been established that the main trends in the development of precision seed cleaning equipment are the creation of adaptive control systems that allow dynamic optimization of operating modes of the working bodies without operator intervention.
