"Indications are that after the 1960s and 1970s breeders have been able to again increase the diversity in released varieties. Thus, a gradual narrowing of the genetic base of the varieties released by breeders could not be observed."
See here graph of 20thC wheat genetic diversity from Wouw et al 2010 https://t.co/8HPHRAKaPB A major trend that increases genetic diversity is use of wild wheat relatives in breeding. I'm confident that since the 1990s, when this graph ends, diversity has
