The main objectives are: 1- To express the maximum variability of growth, both at the larval stage and at the adult stage, in an oyster population originating from parents of various origins. 2- To check the persistence over the time, of growth performance and related physiological functions. 3- To explain the observed growth differential by physiological functions studied. 4- To establish whether the growth differential and the physiological functions are associated with a genetic basis, using 2 types of markers (allozymes and microsatellites), and whether these are related to aneuploidy and to the identity of missing chromosomes. 5- To estimate, in a second generation, genetic variance (additivity, dominance) and heritability of growth and of related physiological traits. Also to estimate aneuploidy transmission to this generation. 6- To evaluate the possibility of selection for a better assimilation efficiency. The beginning of a genetic map provides the first step for marker-assisted selection and QTL (Quantitative Trait Loci) location.
