Abstract

Variability of fibre dimensions and wool follicle populations of F1, and F2, generations of Border Leicester x Romney sheep has been compared. Similar comparisons have been made between crossbred sheep and samples of the parent breeds. Mean values for primary fibre diameter, secondary fibre diameter, mean fibre diameter, primary/secondary fibre diameter ratio and secondary/primary follicle ratio of the F1, and F2 sheep were intermediate between those of the parent breeds. Follicle density was higher for the crossbred sheep though little significance can be attached to this. Comparison of variances of F1 and F2, sheep showed that the only significant increase in variability in the F, generation was in diameter of primary fibres.
