【Abstract】 Centre on breeding objectives,the Canonical Selection Index of Landrace Pigs is estimated by combination of canonical analytical and path analytical method.The total heredity progress CGS_v（xi）of trait x_i for Canonical objective trait（V）can be differentiated in parts: direct contributionC_i of trait x_i and indirect contributionΥ_pijC_j of trait x_i via trait x_j.It can help in the understanding of weight and function of each trait in Canonical selection index.更多还原
