¹ GFW—greasy fleece weight; CFW—clean fleece weight; Yield—wool yield; MFD—mean fibre diameter; FDSD—fibre diameter standard deviation; CVFD—coefficient of variation of fibre diameter; MSS—mean staple strength; MSL—mean staple length; MFC—mean fibre curvature. ² NZ-DP: NZ dual-purpose sheep which are dominated by NZ Romney, Coopworth, Perendale, Texel and composite crosses of these breeds. ³ SE: standard error.
