Project Number: 5440-21000-030-00
Start Date: Dec 14, 2012
End Date: Dec 13, 2017
Improved perennial grasses and legumes and associated management practices will be developed for use in the Central Great Plains and Midwest for bioenergy production and grazing when grown on land that is unsuitable or marginal for grain crop production. Perennial plant breeding technologies will be used to develop the improved cultivars. Improved management methods will be developed to fully utilize the genetic potential of the new cultivars by enhancing establishment, yields, and utilization by livestock, and all aspects of biomass energy crop production. Basic molecular biology and biochemistry/physiology information will be developed that will improve the breeding and management products. The project is a continuation of a long-term perennial grass project that has plant materials, management, and basic science studies in various stages of development and completion. Research will be conducted on both C3 (cool-season) and C4 (warm-season) grasses because both are needed in the region to maximize the length of the grazing season. Switchgrass, big bluestem, and indiangrass will be the primary C4 species and will be developed for use in both bioenergy and livestock production systems. Smooth and meadow bromegrass and intermediate, tall, and western wheatgrass will be bred for use in cool-season pastures. Native legumes will be enhanced for use with C4 grasses in biomass production systems. Grass technologies from this research when utilized on 6 million hectares in the Midwest could produce biofuels for 15 million cars. Beef production per hectare from pastures with new cultivars and improved management could be improved by 10 to over 25%.
