The rationale for kernel visual distinguishability was to facilitate grain segregation and thus make it easy to recognize a Canadian western red spring versus a CPS type, for example, at the elevator. It was really driven by the desire to have something very easy to segregate in a short period of time.
What we're looking at going forward are a number of options, including affidavit-type systems. On behalf of the seed industry, we think we have a perfect system in Canada to help facilitate segregation. It is the use of our certified seed system. Our certified seed system is really the envy of most other jurisdictions in the world, which don't have such a well-integrated public-private certification system for seed. There's that, and we're also getting to the point of having new technology coming that will help to identify varieties in a relatively short period of time upon delivery.
