摘要：

Production of transgenic maize (Zea mays L.) callus, plants, and progeny from microprojectile bombardment of 2-5-d cultured Hi-II immature embryos is described. Histological evidence indicates that these tissues are amenable to transformation due to surface layer cell division of the scutellum. Two out of every 100 bombarded embryos produced transgenic callus and R(0) transgenic plants were both male and female fertile. Expected segregation of transgenes was observed in progeny. The primary advantage of bombarding these tissues is increased male and female fertility of transgenic plants compared with those produced using long-term callus or suspension cultures.
