The genetic transformation rate of maize is directly affected by induction rate of embryogenic callus-es. Friable embryogenic calluses were induced from immature embryos of maize on N6 induction medium and 28 genotypes with high induction efficiencies were screened from 215 maize inbred lines. The induction efficiencies of 6 genotypes were higher than that of control ‘A188’ and ‘Hi-II’. The genotype ‘JiV130’ confirmed in later experi-ment is the suitable genotype for genetic transformation, and can be routinely used for the production of large num-bers of transgenic plants. This result will be favorable for maize breeding by genetic engineering.
