For the arid zone of the Lower Volga region, grain sorghum is an important forage crop. The paper presents the results of a comparative assessment of grain yield and biomass of breeding lines of grain sorghum in the nursery of preliminary variety testing. The volume of the nursery for the preliminary variety testing was 117 breeding lines. The most productive were the breeding lines of grain sorghum, the grain yield of which reached 3.95 t / ha (line PSI-17 / EV-56); 4.10 t / ha (line PSI-17 / EV-113); 4.15 t / ha (line PSI-17 / EV-55); 4.50 t / ha (line PSI-17 / EV-92) with a yield of 3.75 t / ha of the standard variety Volzhskoe 4. As a result of scientific research, the promising breeding lines of grain sorghum were identified: PSI-17 / EV-56 and PSI-17 / EV-92, which were recommended to be submitted for competitive variety testing. It is advisable to use the breeding line of grain sorghum PSI-17 / EV-54V for early maturity. The breeding lines of grain sorghum: PSI-17 / EV-56 and PSI-17 / EV-90 are planned to be included in crosses to create varieties and hybrids with high grain quality. Breeding lines of grain sorghum: PSI-17 / EV-50, PSI-17 / EV-54, PSI-17 / EV-92 and PSI-17 / EV-127 are planned to be used in breeding for biomass yield.
