This study investigated biomass yield and growth characteristics of 26 Jerusalem artichoke (Helianthus tuberosus L.) clones and assessed it as a bioenergy crop for a semiarid region of the Loess Plateau in China. Genotype, year, and genotype ´ year interaction contributed to differences in crop development, growth characteristics, and biomass yields (dry matter). Generally, biomass yields in 2011 were lower than in 2008, mainly due to a more severe soil moisture deficit in 2011. Shoot and tuber biomass yields (STBY) ranged from 18.9 to 35.0 Mg ha–1 in 2008 and from 16.1 to 24.8 Mg ha–1 in 2011. Clones HUB-2 and BJ-4 produced the highest shoot biomass yield (SBY), amounting to 31.3 and 25.6 Mg ha–1, respectively, in the wetter year but higher drought sensitivity. Clones HUN-2, SD-2, and SHH-1 produced the second highest SBY, which varied between 14.3 and 20.1 Mg ha–1. Clones GZ-1, HEN-1, HUB-1, IM-1, and SX-2 are recommended for tuber production and produced tuber yields >8 Mg ha–1 in both seasons. Clones SD-2 and SHH-1 exhibited drought sensitivity indices
