This line is a breeding component developed via the pedigree method through backcrossing of lines 7PVDC41B, 7PUKC97B and 7PPRP24B. The sterile analogue of the line was obtained on the basis of CMS PET1 cytoplasmic male sterility.
The line is characterized as homozygous for the single-head formation trait. In official documentation, resistance to sunflower pests or diseases is not claimed, and maturity group and plant height indicators are not determined, as they are established for the final hybrids.
