Abstract
Individual responses to selection for high pupal weight in T. castaneum under two types of mating, cyclic full-sib random-mating system and random mating, were observed for 15 generations. No significant differences have been observed between the two types of mating for the selection response, differential selection, realized heritability and the number of larvae per generation. Realized heritability of the pupal weight was 0.33 .+-. 0.02 and 0.42 .+-. 0.02 for the inbred lines and for the random-mated lines, respectively.
