Conventionally, Agrobacterium-mediated transformation used hypocotyls or cotyledonas explants and Coker 312 as its model cultivar, which was via somatic embryogenesis andwas the preferred method for transgenic cotton. The transformation protocol was severelyrestricted by genotype-dependent response. Although some genotypes have beentransformed successfully, low regeneration efficiency of via somatic embryogenesis, aprolonged culture period, high frequency of abnormal embryo development, lowconvers...
