Evaluation location: Kansas, United States
Accessions were randomly selected from the U.S. historic sweet sorghum and planted in Manhattan, Kansas in 2007 and 2008. Values were averaged across two years. Flowering time was recorded as the interval after planting to the time when 50% of the plants in a row had pollen shedding on 50% of the spikelets of the panicle (number of days was converted to CGC approved codes); plant height was the distance from the ground to the tip of the panicle; and brix (a measure of soluble solids) was measured 3-4 weeks after flowering with a handheld refractometer at three nodes (4, 7, and 9) of a typical plant in a row, and the mean was recorded for the row. Stalk lodging was converted to CGC approved codes for lodging.
