Abstract: Restore lines or cultivars Minghui 63. Gu 154 and Jingxidanian with higher, thicker stem were used by crossing method and polycross, the plants with higher, thicker stem and longer, larger panicle were selected from progenies and crossed with Zhenzhu sorghum, then new restore line Tehui was bred from hybridization progenies through 24 generations selection. The biological characteristics, agricultural characteristics and yield performances were compared between Tehui and other restore lines including Minghui 63, 9311, 253, 838, Gui 99 and 207. The results showed that restore line Tehui had a lot of advantages such as higher, thicker and tougher stem, higher heterosis performances crossing with different male sterile lines, etc.
