BASEPOP – A tool to determine individuals or strains to be included in a future breeding programme
A new software tool has been developed to create base populations in aquaculture breeding: BASEPOP. This is one of the first tangible results of the FISHBOOST project. The tool will now be tested in practice. If you are interested in BASEPOP and want more information, please contact Anna Sonesson of Nofima.
The construction of a proper base population is critical to developing a successful aquaculture breeding programme. Avoiding inbreeding is especially important in aquaculture breeding, since a few parents can produce large populations of fish. To aid aquaculture breeders in deciding on which individuals or strains should be used for a base population, the BASEPOP-tool has been developed by Anna Sonesson and Beatriz Villanueva.
The overall idea of the optimisation method used by BASEPOP is to estimate genomic relationships (using genetic markers) within and between strains and use this information to optimise individual or strain contributions to a base population for a new breeding programme.
BASEPOP has the option to either minimise the rate of inbreeding (minimise) or perform a selection where the phenotypic values for traits of interest are maximised with a restriction on the rates of inbreeding (selection). For both options one can choose to perform the optimisation at strain level (strain) or at individual level (individual). In all cases, the average coancestry of the candidates is used to control the rate of inbreeding in the offspring population.
During 2015 you are welcome to join the training session and learn how to use BASEPOP. The FISHBOOST website will keep you posted on the training session.
