МАСЛИЧНЫЕ КУЛЬТУРЫ. Научно-технический бюллетень Всероссийского научно-исследовательского института масличных культур. Вып. 1 (173), 2018

Analyzing Russian and foreign scientific literary sources we presented data on origin, history, current state and development prospects of the confectionary sunflower. We stated main features of confectionary sunflower compared to oil form. There is described perspective initial germplasm of confectionary sunflower from the VIR collection and collections of the other scientific institutions. We consider different direction of products use, requirements to qualitative and organoleptic traits. We stated an important role of bee-pollination in formation of high seed yields. We think it is reasonable to repurpose step by step breeding works to primary development and introduction of confectionary interline hybrids. The further perfection of scientific and research works with confectionary sunflower according to climatic changes is discussed.

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.
