Norman Borlaug: Well, in my mind, I always said, why is it that — by then we’d done testing with the old Minnesota, Montana and Canadian spring wheats — Why is it that those things you can’t bring down? Because we had the yield test with them included, comparing to the new ones. You can’t bring them where the day length is 38 degrees or less, because they’re the lowest yielding wheats when that happens, and yet here are the crosses that came from this. I had been forced by rust to make a second group to avoid a rust epidemic in Mexico. The first ones were Yaqui times — or I should say Marquis times — Newthatch from Minnesota. The second one was Mentana, an Italian wheat crossed to Kenya that had rust resistance. And combining those, this new rust didn’t cause us any trouble.
