Wool staple from fleece, pastoral WA.
Staple strength is an important price factor for many wool types and wool growing regions. However direct staple strength assessments for breeding purposes are very expensive.
The indirect assessment for staple strength, Coefficient of Variation for Fibre Diameter (fibre diameter variability along and across the fibre), is proven to be well correlated with staple strength within a flock, but less so for across-flock comparisons.
AWI and the Department of Agriculture and Food WA have investigated if Coefficient of Variation across the fibre alone, is a better predictor of staple strength for breeding purposes.
