Sorghum has been improved independently for grain, stem sugar, and forage producing cultivars and has large amounts of phenotypic variation with regards to these traits. In this experiment we investigated the production and profile of all above ground tissues that would be useful for biofuel production in a QTL mapping population derived from a cross between ‘Rio', a sweet stem, high biomass sorghum, and ‘BTx623', an inbred grain sorghum. Products assayed were both non-structural: stem sugar, grain starch, oil and protein; and structural: stem and leaf cellulose, hemi-cellulose, lignin, and protein. Few generalized tradeoffs between products were found, and QTL locations imply linkage rather then pleiotropy, encouraging multiple trait improvement. These results suggest that sorghum stover could be improved for bio-products without adversely affecting the grain or developed as a dedicated enriched biomass feedstock to maximize energy production.
