The inheritance of hydrocyanic acid (HCN) production was studied in populations derived from two sorghum ✕ sudangrass crosses. Plants from these crosses were sampled for HCN at two different stages of growth. Data from both crosses indicated that high HCN production was partially dominant to low HCN. The F 2 distributions appeared to be unimodal and continuous. Broad‐sense heritabillty estimates ranged from 41.3 to 68.0. These values indicated that HCN production is a heritable character but may be influenced to a large extent by environment. Highly significant correlations were obtained for HCN levels of F 2 plants when sampled at two stages of growth, although actual levels of HCN differed at the two growth stages.
