This article presents the results of selection work on the creation of the source material of sorghum saccuratum for use incrossings to increase the productivity and quality of the vegetative mass of hybrids in arid regions of Russia. The testconducted in 2020–2021 allowed for identifying three varieties (Flagman, Larets, Kapital) and six breeding lines (L–28/14, L–75, L–35, L–34, L–28 and L–5–1). It should be noted that these lines differ from the varieties with a higher biomassproductivity of 33.28–40.58 t/ha, and the content of crude protein and fat at the standard level is 6.60–8.69% and 1.16–1.90%,respectively. Bioenergetic assessment of the biomass of sorghum saccuratum crops showed that the identified lines were alsosuperior to the zoned varieties in collecting dry matter by 0.67–4.69 tons, gross energy output – by 12.29–83.43 GJ per 1hectare.
