| Outline of Final Research Achievements |
Using the synthetic population that were derived from successive random mating of the WOLF(Widely-diversified Outbred Line Family) populations, we obtained several kinds of WOLF population by randomly crossed with recurrent selection or not. Comparing these populations revealed the breeding potential of improvement how linkage disequilibrium was broken and revealed novel recombinant genotypes were small fragmented. In addition, by comparing these non-selected population and sugar circulation selected population, it revealed a marker that has occurred distortion of allele frequency in accordance with the selection. Moreover, on the basis of the genome diversity data, the simulation research conducted for genomic selection for these WOLF synthetic populations. It was suggested that high efficient breeding for the highly sugar content genotype selection has been shown potentially.
