Variety description

10 August 2026

The hybrid is a conventional (non-GMO) variety that serves as a benchmark of "substantial equivalence" when comparing grain composition, gene expression profiles, and nutritional value with transgenic counterparts, such as the hybrid PR33P67, which contains the MON810 event.

In scientific literature, the variety is classified as a representative of the FAO 600 maturity group. Specific agronomic characteristics, including exact plant height or disease resistance, are not presented in open sources for agronomic use, as the variety is an obsolete sample.
