The present study was undertaken to determine the optimum moisture content to which the seeds of sorghum can be dried without affecting their seed quality as well as storage potential. Moisture content of the seeds was brought to 11+0.2%, 7±0.2%, 5+0.2% and 3+0.2% in a desiccator with silica gel and stored at Medium Term Storage (MTS 8+10C) and ambient conditions for six months. The observation from six months of storage showed that optimum seed moisture content of sorghum for storage was 5-7%. Activity of dehydrogenase, sod, pox which are positively correlated, was found highest in seeds stored with 5-7% moisture content and values for EC was negatively correlated with seed quality, which was minimum in seeds stored with 5-7% moisture content. Least survival was found in control having moisture content around 11+0.2% and ultradried (3+0.2%) seed lot, irrespective of the genotype studied.
