Interpretive Summary: The sorghum germplasm line A. and B.Tx3363 was developed and released by the Texas AgriLife sorghum breeding program in 2012. This germplasm line has a black seed color that has been associated with healthy phenolic compounds. These specialty compounds are well documented to have health benefits due to increased antioxidants. This germplasm line in hybrid combination with the black pollinator line Tx.3362 allows for the creation of the first temperately adapted sorghum hybrid with a black pericarp. This release is important to anyone interested in commercial production of health compounds associated with black sorghum.

Technical Abstract: The sorghum [Sorghum bicolor (L.) Moench] germplasms A. and B.Tx3363 (Reg. Nos. GP-___) were developed and released by Texas Agrilife Research sorghum breeding program in July 2012. Tx3363 is a grain sorghum seed parent designed to produce a very dark-colored (ie, black) grain hybrid in combination with R.Tx3362. The color is associated with high levels of 3-deoxyanthocyanins in the pericarp of the grain. This class of compounds is unique because the compounds and the color they impart are extremely stable during processing. Therefore, they have application as natural colorants in many processed food products and they are easily concentrated by processing the bran fraction.
