This study was conducted to investigate the progress in productive and Reproductive performances of two line indigenous chicken genotypes namely Tanta G-2and Mamourah line (RBC) being crossing and selected since 2015 three generations data on body weight  from hatch until 8 weeks also  age at sexual maturity (ASM), egg production (EP) from 36-42 weeks of age and  first egg weight (EW)  and body weight at sexual maturity (BWSM) The average LBW of Tanta G-2and RBC lines by generation at 8 weeks of age were 907.86 g vs. 558.56g (G1), 1088.12 g vs. 554.92 g (G2), 1175.93 g vs. 551.28 g (G3), respectively, with significant differences for both lines This value was 3267gm for the  Tanta G-2and 1525 gm for the RBC line , 3302 gm for the Tanta G-2and 1526gm for RBC line in generation 2 while This value was 3337gm for the  Tanta G-2and 1527gm for the RBC line in generation 3. Age at sexual maturity of the Tanta G-2line was 182 days compared to 155 days for the RBC line in the first three generation that egg weight of the first egg of the Tanta G-2 line (51.66gm) was higher than that of the RBC line (34.65gm).The results indicate that genetic improvement programs has made significant progress through increasing the mean of economic traits selected in indigenous chickens Egypt.
