The screened 32 BAC clones have an average insert size of 114.2 kb with a range of 30–190 kb. They are the first set of C-genome BAC clones screened from B. napus genomic BAC library. The average insert size of this set of BAC clones presented that the constructed BAC library had a high quality. This set of BAC clones can be used as markers to identify individual chromosomes of B. napus C-genome.展开更多
