Abstract
This study was conducted to estimate heritabilities, genectic and phenotypic correlations on economic traits in three strains of Korean Native chickens (KNC) : Black (B), Red Brown (RB) and Yellow Brown (YB). The data used in this study were collected from 2000 to 2007 in the National Institute of Animal Science and a total number was 14,421 birds. The effect of the strains analysis showed that the strain B were greater than the other strains for body weight at 150 days and 270 days. The number of egg production at 270 days of the strain YB was higher than the other strains. The estimated heritabilities age at $1^{st}$ egg, body weight at 150 days, egg weight at $1^{st}$ egg, body weight at 270 days, egg weight at 270 days and number of egg production at 270 days were 0.32, 0.50, 0.31, 0.43, 0.48 and 0.69 for strain B; were 0.42, 0.41, 0.19, 0.48, 0.44 and 0.76 for strain RB; were 0.44, 0.52, 0.24, 0.54, 0.51 and 0.66 for strain YB respectively, The genetic and phenotypic correlations were also estimated.
