Transformation: Initial maize transformation services will use immature embryo and Agrobacterium techniques (Armstrong CL, Green CE, Phillips RL.1991. Development and availability of germplasm with high Type II culture formation response. Maize Genetics Cooperative Newsletter 65: 92-93). This will be focused on Hi-II with a cultural B73 derivative anticipated to be available soon. Research is underway to develop procedures for inbreds including B73 (the genome reference inbred) as well as some elite ex-PVP genotypes.
