Background Energy Sorghum Development
◉ high biomass yield◉ Structural carbohydrates◉ Non-structural carbohydrates
◉ drought tolerance◉ established production systems◉ annual life cycle◉ genetic resources and potential
for further improvement
◉ Optimization within Constraints

Background and Goal Assess the productivity and
composition of sorghum as a bioenergy crop using a diverse set of sorghum genotypes ◉ Five years◉ Eight locations
Look at production logistics, extended season on hybrid choice and planting times.
