For over eight years, researchers at the University of Minnesota have been honing the commercial viability of 'Kernza'. It is genetically similar to wheat, but avoids the environmental damage associated with annual crops. Giant food corporation General Mills recently started producing 'Kernza' cereals, but progress has been slow due to unpredictable yields. “95% of that (first) crop failed. There were some tears shed in our offices here”, says Carla Vernón, president of the natural and organic unit. But there is optimism around a grain that is higher in protein and fibre than wheat. “It could become a win-win for everybody”, says farmer Carmen Fernholz, impressed by the cutback on soil disturbance.
