Our oldest and largest seeded variety used in dual production systems for fibre and grain. CRS-1 has often been used in organic production systems for additional weed competition thanks to its tall stature.  


CRS-1 end use varies based upon where it is grown. Currently, it competes well as a fibre variety in the northern latitudes of Canada. In the USA, CRS-1 is not as tall, resulting in good harvestability for both organic and conventional systems.
