Abstract: 
Genomic selection (GS) has successfully been used in plant breeding to improve selection effi¬ciency and reduce breeding time and cost. We are currently investigating the use of GS to improve breeding for agronomic traits in CSIRO’s cotton breeding program. A training population of 923 upland cotton accessions phenotyped for fibre length and strength was genotyped with a CottonSNP63K array and 18,123 single nucleotide markers were polymorphic. We used these data to investigate the potential for GS as a breeding tool in cotton to predict fibre length and strength traits. Preliminary results and challenges will be discussed.
