Cotton fiber is usually tested in bulk form utilizing a mass or beard of fibers to be presented to a test instrument for measurement.  There are many reasons for this, not the least of which is that handling single cotton fibers is tedious and time consuming.  Cotton breeders are being pushed to make decisions on which new lines and germplasm to pursue and which to abandon.  Cotton breeders are relying on smaller and smaller samples to make these decisions.  Single fiber testing may allow for more data to be provided to cotton breeders than is currently available.  Single fiber testing also allows for the distributions of the measured properties to be gathered.  The Favimat single fiber tester was utilized to measure cotton fiber fineness, strength, and elongation.  The results of the single fiber testing were compared to bulk fiber measurements from instruments such as the HVI and AFIS.
