Interpretive Summary:

Technical Abstract: Delinting seed is common practice in cotton breeding programs. The predominant method of delinting cotton seed is acid delinting. Acid delinting can be dangerous and effluent disposal is difficult and costly. Current research on mechanical delinting proposes an alternative to acid delinting. A prototype developed by USDA-ARS Cotton Production and Processing Research Unit in Lubbock, TX is being tested to explore the potential advantages and disadvantages of using a mechanical delinter for small breeder samples. Variables evaluated include seed carryover, cantilever brush configuration, efficiency, and incidence of seed-borne disease. Overall design, logistics, and practicality of the machine are also being evaluated. Results show the mechanical delinter can be a valuable tool for breeders due to ease of use, safety, effluent reduction and potential linter value. Seed carryover issue needs to be addressed in future designs for practical application in breeding programs.
