The population genetic information about genetic distribution, variation and heterozygosity of Myf6 gene in five purelines and three crossbreds of chicken was analyzed using PCR-SSCP. And the genetic effects of Myf6 gene on fiber density and partial carcass traits were investigated. Only one mutation G/A at base position 47 of the whole CDS was found among individuals in each line. The distribution of Myf6 genotype strayed off the Hardy-Weinberg equilibrium and the heterozygosity was low in two purelines but not in three crossbreds. The wild-type allele A had significant positive effects on live-weight, carcass-weight, breast-muscle-weight and leg-muscle-weight (P0.05), but had negative effects on most of meat quality traits. The A allele had additive effects of increasing 45.54 g of the live-weight, 41.03 g of the carcass-weight, 6 g of the breast-muscle-weight, 9.775 g of the leg-muscle-weight. The A allele had dominant effects of increasing 1.025 μm of the diameter of muscle fiber, 29.99 mm2 of the density of muscle fiber.
