GROWERS of superfine wool are using DNA technology to improve fleece and flock quality.

Genomic testing of young rams can now accurately predict the quality of the wool from their progeny.

Previously, high-value traits such as adult fleece weight could be measured only late in life.

Recently, the head of the Co-operative Research Centre for Sheep Industry and Innovation James Rowe told a seminar in Canberra these traits could now be accurately predicted in young rams using DNA analysis.

He said Merino breeders and superfine wool producers could now make earlier selection of their breeding stock.

"DNA tests can now be used to produce predictive research breeding values, which are based on a blend of new genomic technology and the conventional measurement techniques, which support Australian sheep breeding values," Prof Rowe said.

"ASBVs are the most practical way to objectively assess and select for or against a variety of traits."

The delivery of DNA-based breeding values comes from research led by the Sheep CRC, through its information nucleus flock and genomics pilot projects.

The results have been delivered to producers using MerinoSelect and LambPlan.

The Canberra seminar was run by the Australia Superfine Wool Growers Association, an international association of superfine wool growers and processors founded to ensure a viable superfine Merino wool industry.
