REMEMBER | perennial vs. annual

Wes Jackson has been domesticating intermediate wheatgrass at the land institute since the 1970s.
Workers separate seeds form the chaff of intermediate wheatgrass samples using a dehuller. These will be carefully analysed by researchers. Each successive planting brings Wes closer to his goal, that of replacing annual wheat with more sustainable perennials. According to Wes, the domestication of wheatgrass is expected to take ten to twelve years, after which a commercially viable wheatgrass will become available.
