The method of Agrobacterium-mediated transformation is the most widely used in genetic transformation. To this day, only several genotypes such as Bobwhite and Yangmai158 have been used in transformation successfully. To widen the recipient genotypes, ten different genotypes were transformated by Agrobacterium-mediated In our study, transformation efficiency of B31706 and B31575 were significantly higher than Bobwhite. Moreover, regeneration rate and resistant plantlet rate of Agrobacterium-mediated genetic transformation in B31706 immature embryos callus was the highest one among the genotypes.
