Abstract: The in vitro culture of immature embryos or ovules was employed in embryo rescue to overcome imcompatible interspecific hybridization in Gossypium L. It was also an important means in studying embryo and fiber development mechanism. The methods of immature embryo (ovule) culture have been improved since 1935, but they were still relatively complicated. Different mediums should be exploited at the stage of embryo development to achieve the embryo maturation and plantlet format ion. BT or MS were usually used as basic mediums. Cotton genotypes markedly influenced the effect of the culture in vitro. Various combinations and concentrations of IAA, KT or GA were usually supplemented in the stages from immature embryo development to embryo maturation. The concentrations of carbon sources, nitrogen sources and combinations of NO3-/NH4+ played an important role in the culture process.
