I am back working in academia and am in some grass breeding circles. I have also worked in the private ag industry. Real World is just not a big enough company to have created all of these commercially available cultivars across multiple species. First of all, traditional plant breeding takes almost a decade to breed and produce seed that is commercially viable for a single cultivar of a single species. If they were truly breeding their own, they would need to show that it is different (data), file a plant protection patent, and trademark the name. As far as I can tell, they haven't done any of these things. I would not be at all surprised if the RW switchgrass wasn't just Kanlow among a few other already commercially available cultivars.
I understand he needs to put his own spin on all of the products he and his company peddle. For the most part, the ones I've seen do seem like decent products. But the sales pitches were old the first time I heard them.
