Abstract
Abstract Repeatabilities of greasy fleece weight (FW), staple length (SL), mean fibre diameter (FD), quality number (QN), fleece character (FC), and number of Iambs weaned (NL W) were calculated by regressing older records on younger records in data collected from a flock of Perendale ewes. Average repeat abilities of the wool traits were: FW, 0.62|SL, 0.50|FD, 0.71|QN, 0.46|and FC, 0.18. The repeatabilities of the various components of NL W were low. Genetic correlations between records of each trait collected at different ages were also calculated. With quality number, fleece character, and fleece weight there were indications of genotype x age interactions. A low genetic correlation between hogget and lifetime average fleece weight, coupled with earlier estimates of lower heritability of fleece weights in hoggets, suggests that selection on hogget fleece weight is considerably less effective than selection on 2-year-old fleece weight in terms of lifetime average response.
