Selection of Angora goats over the past decades has focused on traits related to fitness,
body weight and fibre production. Research for genetic improvement of the Angora has
been based on quantitative selection and more recently molecular technology has been
applied. Although considerable progress has been made at increasing fine mohair production,
the inability of Angora goats to survive sub-optimum conditions has become a concern.
Selection emphasis on fibre production resulted in unthrifty animals and the South African
(SA) Angora industry is still hampered by the loss of young goats. DNA marker information
assists conventional selection by increasing selection accuracy, improving the rate
of genetic improvement and leading to a better understanding of the physiological background
of traits. The genetic diversity of the SA Angora goat breed was estimated and an
improved linkage map was recently developed. The extensive production systems in South
Africa pose a challenge for pedigree integrity, and a microsatellite panel was constructed
for parentage verification. Selection for quantitative trait loci (QTL) will lead to increased
genetic progress and offers the opportunity to improve understanding of and exploit phenotypic
variation. Putative QTL associated with fleece and growth traits have been identified
in the South African Angora goat population. The current goat SNP chip does not include
any fibre-producing goat breed, and this chip is currently being verified in the SA Angora
goat population, in conjunction with the sequencing of certain keratin genes
