October plantings showed fewer (P = 0.05) seed infections and less discoloration. &nbsp;<em>Fusarium semitectum</em> (7 to 21%) was the dominant seed microorganism. Stored seed (December to June) lost about 50% of its vigor and size without losing germination (89%). <em>Bacillus licheniformis</em>, with up to 37% incidence, was the dominant seed storage microorganism. Storage microorganisms included <em>Aspergillus</em> spp., other <em>Bacillus</em> spp., <em>Penicillium</em> spp., <em>Chaetomium</em> spp., <em>Mucor</em> spp., and <em>Flavobacterium</em> spp. <em>Fusarium</em> spp. varied in their recovery after storage. <em>Fusarium semitectum</em> was eliminated in storage, whereas <em>F. equiseti</em> increased. Levels of <em>Fusarium</em> spp., in recently harvested seed, and <em>Bacillus</em> and <em>Aspergillus</em> spp., in stored seed, were excellent indicators of seed quality losses in the field and storage in Honduras. Germination data alone was not a good indicator of seed quality because low vigor seed had excellent germination.</p> ER -
