A total of 1,100 newly hatched of Mia chickens with characteristic morphological features, were selected from the Mia population in Son Tay town, and raised for evaluation of growth performance at Hadinco Farm. At 8 weeks of age, blood samples were taken from the wing veins of each individual and were identified the genotype by PCR-RFLP method.The results showed that the A3971G polymorphism of the INS gene had 3 genotypes AA, AG and GG with a frequency of 29%, 55% and 16%, respectively. The T3737C polymorphism had 2 genotypes CT (78%) and TT (22%) no CC genotype was found. The C423T polymorphism has 3 genotypes CC, CT and TT with frequencies of 21%, 45% and 34%, respectively. The polymorphism of G662A had 3 genotypes, in which genotypes AA and AG had frequencies of 51% and 40%, respectively. All of the above genotypes did not have a significant effect on the weight of Mia chickens, while those carrying GG genotype of the G662A had bodyweight higher by 10.4% in the general population. However, the number of Mia chickens carrying this genotype in the population was very low, accounting for only 9%.
