The line was developed using the pedigree selection method based on the cross T0001LG // T9811LG / B0529LG. It is designed for use in hybrid combinations and is not a commercial variety intended for sowing by agricultural producers.
A key feature of the line is its resistance to the herbicide tribenuron-methyl. Selection also took into account indicators such as earlier flowering, reduced plant height, yield, and oil content in the composition of hybrids.
