Abstract: 

This study was conducted at the Animal House Research Center at the University of Aleppo, on a flock of  Inbred local quail (200 birds), consisted of four color groups (white, cream, striped and black) in 2019, to estimate genetic parameters of egg production and quality traits (Heritability, Genetic Correlation, Repeatability, Genetic response). Results showed that the heritability values ​​for some traits were close to the values ​​of heritability recorded for international standard strains, and the highest value recorded for the number of eggs was in black quail (0.71). The genetic correlations of some egg quality traits were positive and others were negative. As for Repeatability, it was found that its values were relatively less than the values recorded in previous studies. As for the estimates of Genetic response for some traits, they were positive for some traits and negative for others, due to inbreeding.

Keywords: local quail, inbreeding, Heritability, Genetic Correlation, Repeatability, Genetic response.
