This paper describes a new method of determining seed coat fragments (SCF) which takes only fifteen minutes per sample. The method utilizes the Shirley Analyzer for detecting cottons having a high SCF potential. This procedure allows for evaluating 4 times as many samples in the same time unit, reduces the CV% and separates the cottons with high SCF potentials from cottons with a low potential. The analysis over-years suggests that cottons could be more accurately ranked with a larger number of samples.
