Abstract: In the study, the fragment PR8 related with Verticillium wilt resistance was used as a probe to screen Bacterial Artificial Chromosome (BAC) library of a Sea Island cotton, Pima90-53, with good quality and high Verticillium wilt resistance. Four positive BAC clones, 127K13, 128D14, 169J3 and 178C5, were detected from 30336 BAC clones. The BAC clone, 169J3, was digested with Sau3AI. After digestion, 2-4 kb fragments were collected and ligated with pUC118BamHI2BAP to construct a sub-clone library. The library contained 4224 clones, and inserts DNA ranged from 1 kb to 3 kb, averaged 2 kb. The sub-clone library could be used for obtaining the complete sequence of Verticillium wilt resistance gene.
