　　　　In general, this study presented the construction of a high-quality BAC library for the genome of Chinese cultivated peanut.Many essential experiences were summarized in the present study. These experiences will be valuable for the production of Arachis or other plant BAC libraries. This BAC library will be a substantial platform for the isolation of novel genes especially associated with oil content, the screening of BAC clones identifying specific chromosome (Wang et al., 2010; Yan et al., 2012), the isolation of characteristic repeat sequences (Li et al., 2010; Nielen et al., 2012), the exploitation of SSR marker for the construction of physical and genetic maps (Qin et al., 2012), and for the study of the genome re-sequencing of Chinese peanut cultivars.
