Variety description

10 August 2026

The hybrid was created at the Institute of Oil Crops under the guidance of Boris Kirillovich Litovchenko. The hybrid's name is associated with the researcher Alexander Nikolaevich Ryabota, who contributed to the development of heterosis breeding of sunflower and the creation of hybrids based on male sterility.

The intended use of the variety is for oil production. Detailed morphological characteristics, such as plant height, maturity group, or precise disease resistance indicators, are not detailed in open scientific publications.
