Abstract

Genetic correlations were estimated among retail colour stability and fresh meat colour traits assessed on Merino lamb loins, as well as genetic correlations of the colour traits with lean meat yield and objective eating quality traits of intramuscular fat and shear force. The meat colour traits were confirmed to be heritable. Improving intramuscular fat or shear force is expected to lead to less redness and faster rate of browning of the meat during retail display. Selection for lean meat yield is expected to improve slightly retail colour stability.
