Interpretive Summary: Cotton fiber elongation has been neglected by breeders due to limitations in high-speed and high-volume testing of elongation. Researchers at Texas Tech University have developed new calibration materials to allow for elongation to be tested on high-volume instruments and the results to be compared between instruments. ARS researchers conducted an independent assessment of the performance of these calibration materials on 10 instruments located in four laboratories.

Technical Abstract: The textile industry is ever evolving and with that evolution comes the need for improved cotton fiber quality. In order to provide the supply of raw material needed by the textile industry, cotton breeders are continuously working to improve cotton traits. One are that has largely been ignored is elongation-to-break. The cotton community has ignored elongation due to the inability to rapidly test large numbers of samples and compare the results between laboratories. To address this shortcoming researchers have developed calibration materials for the measurement of elongation. The efficacy of these standards has been tested in an international round trial. The round trial results demonstrate that cotton fibre elongation may be successfully measured on HVI lines when results are adjusted through the use of elongation standards.
