	abstract = {Wool from lines of Romney sheep selected on the basis of staple strength  
was measured for mean fibre diameter using both the airflow apparatus and an  
Optical Fibre Diameter Analyser (OFDA).  For wool from "low strength" and  
"control" selection lines, airflow measurements tended to be upwardly biased  
in relation to the OFDA measurements, while for wool from the "high  
strength" line the airflow measurements tended to be downwardly biased.  Two  
sources of bias are known in the literature, medullation and standard deviation.   
In this work the latter seemed to be more important, which may be a  
consequence of the relatively low level of medullation present in these wools  
(8.6\%).  For research work the OFDA is put forward as the preferred  
instrument. },
