Abstract
The data pertaining to 372 pullets in base generation (S0) and 434 in S1 -generation of ‘M’ line of WLH were used to study the inheritance of performance efficiency index (PEI) and its various economic traits. The PEI at various productive periods viz. 28th week, 32nd week, 36th week and 40th week were calculated. The averages of PEI at these periods were found to be 23.31 ± 0.33, 27.45 ± 0.30, 25.45 ± 0.33 and 26.45 ± 0.34 in S0 -generation and 26.47 ± 0.32, 28.48 ± 0.26, 30.53 ± 0.22 and 31.06 ± 0.29 in S1 -generation, respectively. Both the generations differed significantly for PEI28, PEI36 and PEI40.
