Sugar content — grain sorghum
Sorghum bicolor (L.) Moench subsp. bicolor
For grain sorghum, stem sugar content is not a target trait, as the plant's metabolism is directed toward starch accumulation in the grain.
In the reference 15 varieties crop Sorghum, where this is mentioned in the description.
Unlike sweet sorghum varieties, grain sorghum is characterized by a dry or pithy stem, where the accumulation of water-soluble sugars is minimal. The plant's energy metabolism is focused on starch synthesis in the caryopsis, which makes sugar content in the stems a secondary trait not used for breeding purposes.
The total sugar content in grain sorghum is approximately 1–3%. In the breeding process for grain varieties, priority is given to grain weight, protein content, and the absence of tannins, as selection for stem sugar content physiologically competes with grain yield.
