Interpretive Summary:

Technical Abstract: Numerous seed abnormalities have occurred in South Carolina cotton fields during the past four growing seasons. Affected seed are poorly developed and often hollow, while less affected seed are pinkish in color and partially hollow. Some seeds exhibit uneven thickening and development of the seed coat. Bolls in which abnormal seed development is detected do not mature normally and are often hard-locked, i.e., unharvestable with a mechanical picker. The objectives of this research were to evaluate the susceptibility of specific cotton varieties to seed developmental problems, to evaluate the response of this phenomenon to determine the potential economic impact of this disorder, and to identify the causal factor(s) and/or organism(s) associated with this problem.
