Abstract :The animal material of the study consisted of quails of similar live weight selected from a randomly mated 14-week-old flock. Selected 29 male and 29 female quails were placed in individual cages with a ratio of 1-1 male females. The chicks obtained from this flock were fed ad libitum with 24% crude protein and 2900 kcal/kg metabolic energy from hatching to the sixth week of the experiment. The sexes of those who completed their development up to three weeks in growth cages by marking were determined and placed in special cages one by one according to their genders. In the study, 86 quails belonging to each family, including 3 siblings, were used. At the end of the trial, the survivability decreased to 75.58%. When considered as the sum of Male+Female, it is seen that the average of the starting weight is 8.776 g, the final weight measurement is 176.16 g and the average weight is 86.47 g. While this average weight is 85.06 g in females, it increases to 87.43 in males. Considering the average heritability, it was clearly separated from the others with a heritability value of 0.586 and this was found to be statistically significant (P<0.05). While the heritability for males was 0.428, it was found to be 0.269 for the total herd. It is seen that the genetic variation for Male, Female and Male+Female was significantly higher in the first generation but decreased with the second generation. It is seen that genetic variation is significantly higher in the first generation for Male, Female and Male+Female, but decreases with the second generation . When we look at the additive genetic change, it is seen that there is a similar change. As seen in this study, it is necessary to pay attention to the changes in breeding activities, especially in the weeks when the genotypic correlations are high.Keywords : Bıldırcın, Kalıtım Derecesi, Genetik Korelasyonlar, Verim.
