	abstract = {Colour is an important characteristic affecting wool price. Canary  yellow wool incidence is low in dry years but individuals can be  classified according to their degreee of susceptibility to wool  yellowing based on results of wool incubation test.  Australian Merino, Corriedale and New Zealand Romney populations were  tested. A number of 603, 1269 and 476 progenies and 21, 52 and 24 sires  were used for these populations, respectively. Susceptibility to wool  yellowing (YPC), greasy (GFW) and clean fleece weights (CFW), yield (Y)  and mean fibre diameter (MFD) were analysed in a sire model.  Heritability values for YPC were 0.21+/-0.11, 0.28+/-0.08 and 0.19+/-  0.07 for Merino, Corriedale and Romney, respectively. Genetic  correlations between YPC and other traits were 0.04+/-0.31 with GFW, -  0.10+/-0.31 with CFW, -0.11+/-0.29 with Y and 0.51+/-0.29 with MFD for  Merinos; 0.30+/-0.18, 0.17+/-0.19, -0.12+/-0.18 and 0.33+/-0.19, -  0.12+/-0.18 and 0.33+/-0.19 for Corriedale, respectively, and 0.77+/-  0.22, 0.44+/-0.31, -0.70+/-0.35 and 0.25+/-0.30 for Romney,  respectively. Phenotypic correlations were negligible among this traits  for these three populations, except for YPC and Y (-0.33+/-0.10).  Selection strategies to reduce wool yellowing susceptibility will differ  between genotypes. Low frequency of susceptible sheep in Merino  population showed little justification for including YPC in genetic  programmes for this particular breed only.  },
