Broiler male line (PB-1) and female line (PB-2) were under continuous mass selection for 6 week body weight and independent culling level was applied for 40 week egg production in female line. Data obtained over 5 generations on juvenile body weights and production traits was analysed to evaluate the short-term direct and correlated responses in both lines. In male line, genetic responses for 6 WK body weight, 20 WK body weight, age at sexual maturity,32 WK egg weight ,40 WK egg weight and 40 WK egg production were 31.6±21.31g, -80.10±111.98g, -38.60±102.58g, 0.50±2.31days, 0.24±2.40g,-0.49±0.81g and 1.80±4.69eggs respectively. On genetic scale 6 WK body weight was improved significantly(P
