    Gossypium%interspecific hybridization%breeding system


    The new technique of interspecific hybridization was created in Gossypium, which could remarkably overcome abortion of interspecific hybridization and hybrid sterility of F1. A large number of germplasm resources were obtained from seventy cross combinations among the cultivated species and between the cultivated and the 14 wild species, respectively. 8 varieties have been developed, of which 4 were from the cross combination of G . hirsutum×G . arboretum and the other are the first breed from the hybrids between G . hirsutum and 4 wild species, respectively. Of them Shiyuan 321 (jimian 24) is a new variety which had the highest increase in the national Yellow River Valley Regional test, with planting area added up to 933333 ha in the recent three years. The breeding system of interspecific hybridization was established.
