Classification based on tannin conc	Sorghum grain color	Pericarp color	Testa pigmentation	Tannin conc	Phenolic profile	Resistance to mold and bird attack
Type I sorghums	White	White	No	No	Very low	Low resistance
	Yellow	Yellow	No	No	Low	Low resistance
	Red	Red	No	No	Moderately high	Low resistance
Type II sorghums	Brown	Red	Yes	High	High	Highly resistant
Type III sorghums	Black	Red	No/Yes	Varies	High	Moderately resistant
