In this study, Japanese quails were divergently selected during 5 generations for high and low 5-week body weight. Egg production in randombred, low and high line were obtained as 79.54-88.96, 77.36-85.92 and 67.3384.58 % from 80 to 95 days. Age at first egg in lines were 39.82-45.84, 42.10-51.10 and 40.11-46.07 days, egg weights were 11.18-12.18, 10.94-11.49 and 12.01-13.23 g, hatchability were 51.35-55.03, 51.22-61.98 and 48.00-53.48 %, fertility of eggs 82.94, 87.39 and 86.79 "4 in generation 5. In generation 0, viability for 5 week was 85.28 %, after selection for three lines were 80.38, 80.02 and 78.86 %, respectively.
