Variety description

10 August 2026

The EXP258B line is used by research organizations and companies as an isoline or genetic analogue. It serves as a non-modified reference standard when conducting laboratory research, testing for the presence of genetically modified organisms, and creating certified reference materials.

This material is used as a baseline genetic analogue for comparison with various GM lines. Agronomic characteristics, such as yield, maturity group, or disease resistance, have not been determined for this material, as it is not intended for commercial agricultural production.
