	abstract = {Farmers have been attempting to breed whiter wool for some time using quantitative and subjective genetic selection based on phenotypic traits. The improvement of wool colour using this form of selection has achieved limited success. The advent of DNA marker maps has introduced the possibility of more directly relating phenotypic and genetic variation. Work presented here has identified a total of ten potential quantitative trait loci (QTL) that are significant at the suggestive level, and one additional QTL that approached this significance threshold that influence wool colour. There have been five putative QTL identified for base colour or challenge colour brightness. Two QTL affecting challenge colour yellowness was identified, while three QTL identified were linked to predictive colour variation. An additional QTL that affected predictive colour has also been mapped to a non-specific location on chromosome 24. Several further key areas of research need to be addressed before the DNA markers can be developed for use in the improvement of wool colour. },

	abstract = {Wool follicle traits and mean fibre diameter (MFD) of {\textonehalf} Merino {\textonehalf} Romney F{\textonesuperior} (MR), and {\textthreequarters} Merino {\textonequarter} Romney backcross (MRM) were compared. Skin and midside samples were collected from 25 ewes and rams of MR and 420 MRM progeny. MRM was lower than MR for MFD by 3.0 mm, follicle fibre area (FFA) by 162.4 mm{\texttwosuperior}, and diameter (FFD) by 4.1 mm, but greater for total follicle density (DEN) by 21.7 mm-2 , primary density (PD) by 0.8 mm-2 , and secondary to primary ratio (SPR) by 4.8 units. Most traits had significant differences (P<0.05) for birth year, breed and sire group, but only PD and SPR were significant for sex and birth/rearing rank. FFD was positively correlated (P<0.001) with MFD (r = 0.22), and the relationship had a common slope of 0.7, but intercepts were significantly different (P<0.01) across birth years (i.e. 13.5, 12.0, and 10.9 mm for born 1991, 1992, and 1993). },

	abstract = {A gene mapping flock for wool traits was established by backcrossing  of Merino cross Romney (F1) to both parental breeds. The objectives for  this flock were to investigate the segregation of wool and skin characteristics  in crosses between the Merino and Romney and to investigate methods for  the analysis of genetic markers and quantitative trait loci. Analysis of  Merino backcross animals showed no evidence of major genes segregating  for any of the wool traits studied. The analysis estimated a finite number of  genes affecting fibre diameter and bulk. A genetic marker study of these  family groups may provide more powerful analysis for the presence of genes  affecting wool traits that may be segregating in these crosses.  },
