Session 5.01: Genetic dissection of bioenergy traits in sorghum

Sorghum is a C4, diploid, annual plant with high yield potential and low input requirements.  It is produced as grain sorghum, forage sorghum, or sweet sorghum.  The third of these is the species in use in this study, and is much like sugarcane in its sugar outputs.  The efforts in this study aim to minimize water, nutrient needs and fertilizer, and to maximize grain, biomass, and sugar.  The study used several mutant genes in the sorghum to find an optimal strain.  Using QTLs, the study looked at drought tolerance, sugar yields, and cropping styles.
