1 GFW—greasy fleece weight; CFW—clean fleece weight; YIELD—wool yield; MSL—mean staple length; MSS—mean staple strength; MFD—mean fibre diameter; FDSD—fibre diameter standard deviation; CVFD—coefficient of variation of fibre diameter; PF—prickle factor (percentage of fibres over 30 μm); MFC—mean fibre curvature. 2 Predicted means and standard errors of those means derived from the GLMs. 3 p values < 0.05 are in bold, and p values < 0.10 are italicised.
