Line 7Pdvn12r was developed using the pedigree method with backcrossing by crossing lines 7PCRT80R*4 and 7PBHY67R. The object is a linoleic oilseed fertility restorer line and is intended for use exclusively in breeding work.
During the selection process, selection was carried out for early flowering, reduced plant height, and increased yield in hybrid combinations. There is no officially stated resistance to diseases, pests, or herbicides. Hybrids based on this line are adapted for cultivation in the northern regions of the USA and European countries.
