Abstract: During the period 2016-2017, some of the basic morphological and biochemical characteristics of seeds in Sorghum species are studied, including seed size (mm), eccentricity index (EI), seed coloring, and color of pericarp. Some of the basic biochemical parameters - crude protein (SP), crude fat (SM), phosphorus (P), calcium (Ca), magnesium (Mg), water soluble sugars, total polyphenols (mg GAE/100g) as well as antioxidant activity (μmol TE/100g) were studied in laboratory conditions. It was found that the coloring of the seeds of S. bicolor
and S. halepense is in red color tone (a is 6.26 and 6.79), while the coloring of the seeds of S. sudanense and S. vulgare var. technicum is in the yellow-orange color tone (b is 12.73 and 15.62). The ratio of red and yellow color
