The hybrid is a commercial variety adapted for farming systems requiring post-emergence control of a wide spectrum of weeds through the application of imidazolinone herbicides (IMI or Clearfield technology).
The hybrid plants demonstrate morphological plasticity. Under conditions of high weed infestation density, a reduction in plant height, head diameter, and leaf surface area may be observed.

The primary name shown is the one under which the variety is registered in the largest number of jurisdictions. Search finds the variety by any of its names.
The variety is listed in the national registry — its seeds are authorized for sale in this country.
