Interpretive Summary:

Technical Abstract: Sorghum is a critical crop worldwide, especially prized for its drought tolerance and potential for meeting the needs of a changing climate and growing population. Thus, it is critical that sorghum breeders and producers have access to sorghum genotypes that have superior forage and grain yields. A dominant multi-tillering mutant (mtl-D1) has been identified and presents an important step towards meeting forage demands. The mtl-D1 mutant has shown superior grain and biomass yields as compared to wild-type BTx623 in data collected in prior years. In 2021, the mtl-D1 mutant had mean biomass yields of 65.5 t/ha and the WT BTx623 had 44.8 t/ha, a significant difference according to a t-test (p<.001). For grain yield, the mtl-D1 mutant yielded 23.9 t/ha and WT BTx623 yielded 17.8 t/ha and also varied significantly according to a t-test (p<0.01).
