Since the late 1980s, the rate of grain yield improvement has slowed, and now appears to have reached a plateau. There are several reasons for this, including the perpetual evolutionary arms race against new pathogens, the resurgence of old pathogens, or perhaps merely the exhaustion of available genetic resources for yield improvement. “We truly are in need of a second ‘Green Revolution’ in wheat,” says Graybosch, a wheat geneticist.
