Sure.
To my knowledge, Canada has been the only jurisdiction in the world that has used KVD, or kernel visual distinguishability; for a variety to be registered and fit into a certain class, it has to look a certain way. As time has gone on, that's had the effect of essentially narrowing the gene pool from which we could cross, and thus has had a very negative impact on our ability to register higher-yielding varieties over time. Even varieties that have been an improvement in terms of quality, disease tolerance, and so on haven't been able to reach the marketplace because of that constraint of kernel visual distinguishability.
I think this has really come to a head in the last couple of years because of the new opportunities with ethanol and the need for more feed, and so on, in western Canada, in recognizing that the west needs to have the same opportunities we've been enjoying for close to the last 20 years in the east, where we have been able to make some really substantial increases in yield. It's certainly a very critical issue I think for the seed industry and for all of the downstream sector as well, particularly the feed industry and the ethanol industry, to meet that need for more production overall.
