Research Project:
U.S. Native Grass Breeding Consortium to Identify Regional Optimum Crop Biomass Productivity
Project Number: 3655-41000-004-09
Project Type:
Reimbursable
Start Date: Jul 01, 2008
End Date: Jun 30, 2011
Objective:
1) To identify the optimum selection technique to identify the best performing switchgrass plants (with higher nitrogen use efficiency [NUE]) on marginal land and to identify germplasm of switchgrass that performs best on marginal land in each region; 2) Identify cultivars of switchgrass that perform best on marginal land in each region and identify cultivars that may have broader adaptation across several locations on marginal land; 3) Determine the biomass production of C4 grass and legume mixtures vs. C4 grass monocultures on marginal land in each adaptation region; and 4) Develop new cultivars with improved biomass production for biofuels on marginal land in each adaptation region.
Approach:
Switchgrass cultivars and half-sib families will be evaluated at Hancock and Arlington, WI. The two locations will represent prime farmland and marginal farmland for growing switchgrass as a bioenergy crop. Plots will be planted in 2008 and harvested in 2009-2011.
