"The emergence of this disease is suggested to have been triggered by breeding-related changes in cultivated hybrids, particularly the erosion of genetic diversity."

People have actually been saying the same thing for decades Spring sickness has been known since at least the 1950s and something that sounds like it but without the name was also described in the 1940s (contrary to the article's statement that it was first reported in the 1970s) so it's hardly anything new, plus species daylilies can get it.
