"These plants are the winners, the ones that get to pass their genes on [to future generations]," says Lee DeHaan of the Land Institute, an agricultural non-profit based in Salina, Kansas. If DeHaan's breeding programme maintains its current progress, the descendant of these young perennial crop plants could one day usher in a wholesale revolution in agriculture. The plants are intermediate wheatgrass. Since 2010, DeHaan has been transforming this small-seeded, wild species into a high-yielding, domesticated grain crop called Kernza. He believes it will eventually be a viable " and far more sustainable " alternative to annual wheat, the world's most widely grown crop and the source of one in five of all calories consumed by humanity. Remarkably, DeHaan does not paint the current agricultural-industrial complex as the enemy. "Every disruptive technology is always opposed by those being disrupted," he says. "But if the companies [that make up] the current system can adjust to the disruption, they can play in that new world just the same." The Land Institute's strategy is redirection rather than replacement. "Our trajectory is to eventually get the resources that are currently dedicated to annual grain crops directed to developing varieties of perennials," says DeHaan. "That's our [route to] success." There are signs that this is already working, with the food firm General Mills now incorporating Kernza into its breakfast cereals.
