In 2017–2019 we conducted researches in NPO “Triumph”, Matveevo-Kurgansky district, Rostov region, and in fields of V.S. Pustovoit All-Russian Research Institute of Oil Crops, Krasnodar. The purpose of the research was to develop methodic questions of selection of self-fertile biotypes during production of foundation seeds of confectionary sunflower varieties. We stated self-sterile and semisterile consist the main part of the studied seven OPvarieties and are equal 68.5% in average. They vary from 60.3% in the Enisey variety to 75.0% in Dobrynya. Basing on our researches we proposed a rating scale for self-fertility level in sunflower varieties and a scheme of foundation seeds growing oriented for selection of biotypes with increased selffertility. We developed a promising varietypopulation Dobrynya+, its average self-fertility of plants is equal to 12.2% comparing to 6.5% of the initial variety. A share of the less valuable self-sterile biotypes in it decreased from 22.2 to 12.0%, and a portion of the most valuable highly self-fertile, contrariwise, increased from 13.9 to 18.0%. By a complex of the other economically valuable traits a population Dobrynya+ does not differ of the initial variety.
