Instrument fibre tests indicate that there is no difference between the fibre from transgenic Bt cotton and non transgenic. However there is assumed concern from the spinning and textile sector. To overcome any doubts, and to improve confidence in the Australian transgenic varieties, a full commercial evaluation needs to be undertaken. Similar work with non transgenics has been supervised by the 1Fibre Research Management Group' (TexSkill, Rocklea, Bonds, University NSW, CRDC - plus occasionally CSD, CSIRO and Dr Stuart Gordon). In the past this group has organised parallel assessment by Schlatborst (Germany) and further testing by Zellweger (Switzerland) to add international confirmation.
