Interpretive Summary: Multiple yearly harvests can increase crop productivity but the crop may encounter different environmental challenges (such as early-spring cold or late-fall frost) depending on cultivation zones. Sweet sorghum as a feedstock may be planted early to get a double harvest or be rotated with sugarcane in the same year for bioenergy production in certain Southeast regions of the U.S. For double harvests of sweet sorghum or rotation of sweet sorghum with sugarcane within the same year, we screened sweet sorghum accessions within the USDA germplasm collection for early-spring cold tolerance, double cutting, and late-fall frost tolerance. We identified a few sweet sorghum accessions with good tolerance to early-spring cold, suitable for double cutting, and good tolerance to late-fall frost, respectively. The identified superior accessions will be tested in different locations. Accessions confirmed for cold/frost tolerance and double cutting can be potentially used as parents for developing new cultivars or hybrids in breeding programs.
