Abstract:

Gossypium barbadense L.,has superior cotton fiber quality,good abiotic stress tolerances,and high resistance to verticillium wilt and other biotic stress.It has always been one of the critical research subjects of germplasm improvement and utilization of Gossypium hirsutum L.by recombining exogenous DNA from G.barbadense L..The conventional genetic hybridization technology at genome level,biolistics transformation and pollen tube method for introducing exogenous G.barbadense DNA,and substitution line technology at chromosome level were reviewed.The assessment of attempts from geneticists and breeders in various genetic recombination strategies to deal with the genetic barriers of genetic recombination for these two species were conducted.Chromosome substitution line with G.hirsutum background carrying individual G.barbadense chromosome established by breeders is a prospective solution to develop stable germplasm with elite agronomy traits and/or biotic and abiotic stress tolerances,which will facilitate upland cotton germplasm innovation harboring gene resource from G.barbadense,then accelerate the cotton germplasm improvement.

Key words: Genetic recombination of Gossypium barbadense L.and Gossypium hirsutum L., Conventional hybridization technique, Biolistics transformation, Pollen tube pathway technique, Chromosome substitution lines
