A long-staple cotton variety allowing spinning 150 N to 340 N combed cotton yarns, and a breeding method thereof are provided. In the present disclosure, through a “radiation mutagenesis of Gossypium barbadense (G. barbadense) L.+distant crossing of Chinese G. barbadense L. and Egyptian G. barbadense L. with upland cotton+backcrossing+G. barbadense L. and upland cotton introgression+stepped composite crossing” technology, four excellent parents are subjected to convergent crossing to obtain a long-staple cotton variety. During the selective breeding, through “radiation mutagenesis-screening-distant crossing-backcrossing-selfing-screening-crossing-screening” and “southern breeding+northern breeding”, a large number of excellent genes are combined and aggregated; and through distant crossing of G. barbadense L. and upland cotton, backcrossing, and G. barbadense L. and upland cotton introgression, cell nuclei of G. barbadense L. effectively interact with cytoplasm of upland cotton.
A seed of cotton variety Gossypium barbadense L. BMC69, wherein a representative seed of said variety was deposited under the China Center for Type Culture Collection (CCTCC), Wuhan University, Accession No. P202605.
A method of introducing a trait into cotton variety Gossypium barbadense L. BMC69 comprising:
