Abstract: Bacterial artificial chromosome library is the foundation of important and high quality disease-resistant gene cloning from Brassica oleracea.A bacterial artificial chromosome library was constructed from R4P1,a Brassica oleracea varieties highly resisting to fusarium wilt and being in rich of glucosinolates,with the vector CopyControlTM pCC1BACTM.The library consists of 73 344 clones with an average insert size of about 97 kb,and in which the empty clones are under 3%.Thus,the library provides 10.9 haploid genome equivalents,the probability of screening to any gene of B.oleracea is 99.99%,these results indicate that this is a high quality BAC library suitable for the following analysis.The BAC library of B.oleracea could not only be used for the clone of resistant genes to fusarium wilt,but also lay foundations for isolating other interesting genes and research the genomics of B.oleracea,et al.

Key words: Brassica oleracea, Bacterial artificial chromosome library, Fusarium wilt resistant gene, Clone
