The relationships between the degree of multi-loci heterozygosity in the Philippine Mallard, Khaki Campbell, and the Pekin duck populations based on 21 polymorphic microsatellites and the bodyweight, breast depth, breast width, keel length, and shank length at maturity were determined. The multi-loci heterozygosity was highest in the Pekin with 0.3985 followed by that of the Khaki Campbell and Philippine Mallard with 0.3077 and 0.2711, respectively. In addition, significant correlations were detected between the microsatellite loci heterozygosity and bodyweight at maturity (r = 0.468), breast width (r = 0.410), breast depth (r = 0.443) and keel length (r = 0.449) of the mallard ducks in an overall population basis. This suggests that the individual performance potential of the ducks in these traits could be ascertained early in their life based on the degree of their individual heterozygosity by employing linear regression analysis.
