To follow on that, essentially on the question about KVD, to be very clear, the key grading issues relate to wheat and to KVD. The other concerns and comments that we heard would be a drop in the bucket compared to those particular issues. That's really where some of the malcontent rests, with regard to that and the pressures that you very well identified between competing interests.
That said, it's also generally accepted or acknowledged that we can't compromise the quality that is in place and is perceived by our customers in the very effective segregation that's provided by KVD for those core classes, being Canada western red spring wheat and Canada western amber durum. The process that I think the Grain Commission went through to get there in terms of this recommendation for a new class involved very extensive consultations, according to what we were presented with, so that's what's going to be required as an industry-based approach to move to the next step.
To be very clear, there may be technological changes that help us accelerate in this balance between innovation, which is really what we're talking about, how you foster innovation while preserving and protecting the reputation we have with our existing system, the existing varieties, and the process for registering them.
On the DNA testing, any form of rapid or effective testing, the work is being done now to try to discover that. If there's a breakthrough and it's rapid and cost-effective, this might change very, very quickly.
As to methods to identity-preserve products, the protocols are in place. In fact, Canada, in my view, does a better job than probably anyone else in the world in being able to balance these two things currently. Over one million tonnes per year are sold by the Canadian Wheat Board through identity-preserved or variety-specific programs. The whole designated barley process ensures varietal purity of well up to 95% to 99%.
