| Abstract: | Summary The usefulness of a non-random group selection method in the improvement of a character influenced by interactions among individuals has been experimentally tested in a population of Tribolium castaneum. The selected trait —number of adults produced in a fixed period of time —showed a clear increase after 11 generations of selection. This increase is related to a reduction in developmental time, and it was specific for the population structure in which selection was applied, vanishing when this structure was altered. |
