This study was carried out to compare Msp I polymorphisms in the 3rd intron of porcine gene encoding the pituitary-1 transcription factor (POU1F1) from 286 pigs (Landrace $\times$ Yorkshire $\times$ Duroc, LYD) and to determine the associations between its genotypes and carcass traits by using the PCR-RFLP technique. The frequency of the single nucleotide polymorphism (SNP) genotype DD (84.33%) was very higher than that of CC genotype (0.75%). Allelic frequencies for C and D were 0.082 and 0.918, respectively. Each population followed the Hardy-Weinberg equilibrium. Meat colours of Hunter $L^*$ values and visual colour according to two genotypes were all significantly different. However, no significant difference in crossbred (LYD) was found between CD and DD genotypes for other traits. Therefore, this suggests that POU1F1 may be a major gene or marker for carcass traits.
