In this report, methods of introducing theγ-tmt and bar gene into peanut cultivars(Fenghua1,Baisha1016,Fenghua3 and 79266) with Pollen tube pathway and In Planta transformation were studied. The setting rate and frequency of plantlets of two transgenic methods were compared. The appropriate method of screening transformed gene plants was discussed. The three main pathogenic fungi of peanut were isolated by tissue isolating method and the affecting factors on the mycelium and sporulation of Cercos...
