Narrative

Independence switchgrass (Panicum virgatum L.) was characterized by rapid establishment, robust seedling growth, and the capacity to achieve peak production by the second year. Independence is well-adapted to USDA hardiness zones 5b to 7b. In field experiments conducted from 2016 to 2017, averaged over seven locations and all years, Independence annually yielded 13 Mg ha-1 of biomass, outperforming 'Cave-in-Rock' by 25%, 'Liberty' by 7%, 'Shawnee' by 25%, 'Summer' by 53%, and Sunburst by 78%. In wet marginal sites in Illinois from 2020 to 2023, Independence exhibited an average biomass yield of 12 Mg ha-1, outperforming Shawnee by 31%, Liberty by 27%, and 'Kanlow' by 19%, indicating its potential use on less productive land for annual crops. Independence was publicly released by the University of Illinois at Urbana-Champaign in October 2021. Syn2 seed was produced and will be maintained by the University of Illinois.
