infection of cottonseed (gossypium hirsutum l.) by aspergillus flavus and associated production of aflatoxins are problems in the arid portions of the united states cotton belt. the hard seed (impermeable to water) characteristic confers resistance to these problems in ripened cottonseed. experiments were done to determine if low seed coat permeability to water or impermeability protect developing seeds from deterioration and aflatoxin formation. no differences were observed in the degree of seed deterioration in the various cotton lines that could be attributed to seed coat permeability. it is likely that, because the impermeable or low permeability phenotypes are expressed only upon seed ripening, these characteristics afford no protection to cottonseed against attack by a. flavus during seed development.
