Abstract: Based on estimated breeding value of pupa weight of Tribolium Castaueum by individual animal model, Tribolium Castaueum populations with different sizes were divergently selected for 6 generations for estimation of genetic parameters and evaluation of response to selection. Results suggested that constant progress of estimated breeding value in all selected populations were achieved, the response to selection of pupa weight was asymmetrical,and the realized heritability was in a range of 0. 25一0.56;The genetic structure of base population, population size,generation,selection direction could be important factors affecting estimation of genetic parameters and selection progress;selection progress could be obtained based on breeding value by animal model.

Key words: Tribolium Castaneum, Pupa weight, The breeding value, Genetic parameters, Selection response
