Intermediate Wheat Research
Intermediate wheat grass, also known as Kernza, is a perennial grain and forage crop. It is unique relative to other small grains, like wheat, in that it produces grain harvests for at least three years after planting. Due to its perennial nature, it also promotes soil health and reduces soil erosion with its extensive root system. Researchers are evaluating its contribution to sustainable agricultural practices across the country. The intermediate wheatgrass grown at the Robinson Research Farm is an evaluation nursery for the intermediate wheatgrass breeding program, led by Dr. Lauren Brzozowski (UKPSS). Each plant has been genome-sequenced, and researchers are measuring how fast the plants grow and how much grain is produced to select the most promising individuals to use in breeding new Kentucky-adapted varieties. The nursery is one of four across the state at UK Research Farms and allows researchers to evaluate how well intermediate wheatgrass grows in Eastern Kentucky. This work is contributing to the development of new seed varieties for growers over the next few years.
