sorghum, forage sorghum, variety, rancher, hydrocyanic acid
Rancher sorghum has the lowest hydrocyanic acid content of any named forage sorghum variety in production. It contains about one-third of the hydrocyanic acid content of the low-acid Dakota Amber 39-30-S released in 1937 and only about one-tenth of the hydrocyanic acid content of commercial varieties (Table I). It was developed by the South Dakota Agricultural Experiment Station from a cross of the low hydrocyanic acid strain 39-30-S and a high acid strain 19-30-S and back crossed with the low acid strain 39-30-S. Both strains were selected from Dakota amber variety.
