    This study was conducted to estimate correlations the correlation coefficients and the rank correlation coefficients between the measured at ADGⅠand ADGⅡ, at Selection IndexⅠand Selection IndexⅡ by test methodⅠ,Ⅱ from On-farm tested Yorkshire gilts. The data were obtained from 714 heads of Yorkshire tested KAYA Health breeding Co.,LTD from December,2000 to March, 2001. parameters were estimated by using SAS@8.2 and Excel program The results obtained are summarized as follows ; 1. The means of traits studied were 579.09±1.87 for ADG(g)Ⅰ, 845.61±3.74 for ADG(g)Ⅱ,148.58±0.39 for age at 90㎏(days) and 15.75±0.10 for backfat thickness(mm). 2. The phenotypic correlation coefficients between the measured test methodⅠ,Ⅱ at ADGⅠand ADGⅡ, at Selection IndexⅠand Selection IndexⅡ were 0.824 and 0.870 3. The rank correlation coefficients between the measured test methodⅠ,Ⅱ at ADGⅠand ADGⅡ, at Selection IndexⅠand Selection IndexⅡ were 0.818 and 0.865
