Suitability of eight varieties of sweet sorghum in Xining region

A field experiment was conducted to select the suitable varieties with the higher biomass and saccharinity in stems from introduced eight varieties of sweet sorghum by comparing the growth period, agronomic characteristics, biomass and saccharinity. This study showed that Jiutianzasan, Jitian No.5 and Super herder performed well and their yield (stem and leave) ranged from 5 832.9 kg666.7 m-2 to 6 846.0 kg666.7 m-2. The sugar content in stem and leave was 12.16% to 16.39%. This study suggested that Jiutianzasan was optimal varieties among eight varieties of sweet sorghum for forage production in the Xining region.
