Synopsis The effects of several freezing temperature durations on viability of sorghum seed of varying moisture content were evaluated using maturing seed of four sorghum genotypes. As moisture content of the grain increased and as temperature decreased, progressively shorter durations were necessary to effect reduced seed viability. Durations of as little as 1/2 to 1 hour at 20° and 14° F. caused marked loss of viability in high moisture grain.
