This study aimed to find candidate protein spot as breeding markers. Blood samples were taken from the jugular vein of 94 steers that belonged to progeny test 33 and 35. The samples were subjected to Two-Dimensional Polyacrylamide Gel Electrophoresis. The data used in this study were collected at National Livestock Research Institute in Chonan Korea, as progeny test from 1998 through 2003. The carcass traits considered in this study were cold carcass weight (CW), eye muscle area (EMA), back-fat thickness (BF) and marbling score (Intramuscular Fat, MS). A total of 119 spots on each gel were detected and compared with the reference gel. Based on the statistical comparison of spot intensity among gels, significant spots were selected and determined the correlation analysis with the breeding value of carcass weight, eye muscle area, back-fat thickness and marbling score. The study confirmed the relationship between breeding values of economic traits of Hanwoo cattle and spot intensity. Therefore, the identification of promising targets for detailed analysis by conventional biochemical and/or genetic approaches needs to be undertaken.
