The aim of this research was to study the most important productivity traits of the Syrian costal local hens, this study was conducted in the Animal Production Research Center Fideo, Faculty of Agriculture, Lattakia Tishreen University. An early selection was apply on 1281 local hens eggs. So, two generations were selected during 150 days, the number of the first generation F1 hens were included 163 hens (F1), whereas the second generation F2 were included 169 (F2) to improvement egg production traits. The results of this research showed that the percentage of the egg shape index for the initial flock were 75.8 %. And the fertility of the initial flock record 89.8 and for F1 and F2 hens were recorded 88.7 and 88.2 % respectively, while the hatchability were 75, 82.65, 83.44 % respectively and the hatching rate were 65.54, 68.6, 69.3 % respectively. While for the average egg weight were 50.85, 50.26, 49.75 g respectively, egg number (quantity) were 14.61, 16.22, 17.39 egg/ month respectively. The selection efficiency was increase in the average egg production of the two selected generations by 5.84 eggs. And the percentage of egg production were 49, 54, 58% respectively, egg mass were 24.58, 27.02, 28.72 g/hen/day respectively, and the average of egg productivity were 0.49, 0.54, 0.58 egg/hen/day respectively. The feed conversion ratio recorded 4.6, 4.2, 3.9 (kg feed/kg egg) respectively. In addition, the eggshell color of the produced egg varied from white to light brown gradually. However, the average age of sexual maturity recorded 206, 202, 195 days respectively. These results showed that the selected hens of the two generations F1 and F2 were with superior than the initial flock.
