Abstract: Meat quality such as tenderness, color Density (OD), pH and Water Holding Capacity (WHC) were estimated from breast muscle of genetically fat and lean chickens at 12 week of age. Mutation in lipoprotein lipase and apoVLDL-II genes was detected by PCR-SSCP techniques. Agreement of the genotype frequencies with the Hardy-Weinberg equilibrium expectations was tested using a chi-square goodness of -fit test. Lipoprotein lipase gene frequency was significantly different (p<0.01) in Rugao population, whereas in apoVLDL-II gene there are no significantly different between populations. The populations were differed significantly (p<0.01) within two genes. Lipoprotein lipase genotype was significantly (p<0.05) effect water holding capacity and meat tenderness. However, apoVLDL-II genotype was non significantly affected meat quality traits. The results also indicated that the interaction of Lipoprotein lipase and apoVLDL-II genotype was significantly (p<0.01) effected color density, pH and meat tenderness, whereas it was non significantly effects water holding capacity of breast muscle.
