Breeding of the Crested Wheatgrass Complex (<i>Agropyron</i> spp.) for North American Temperate Rangeland Agriculture and Conservation
2020
Joseph G. Robins | Kevin B. Jensen
Species from the crested wheatgrass (<i>Agropyron</i> spp.) complex have been widely used for revegetation and grazing on North American rangelands for over 100 years. Focused crested wheatgrass breeding has been ongoing since the 1920s. These efforts resulted in the development of 18 cultivars adapted to western USA and Canadian growing conditions. These cultivars establish rapidly, persist, and provide soil stabilization and a reliable feed source for domestic livestock and wildlife. To address ecological concerns and increase rangeland agriculture efficiency, crested wheatgrass breeding requires new emphases and techniques. This review covers the history of crested wheatgrass breeding and genetics in North America and discusses emerging methods and practices for improvement in the future.
