The objectives of our program are to (i) optimize DH technology in maize regarding haploid induction, haploid identification, and spontaneous haploid genome doubling, (ii) employ DH technology, e.g., to establish exotic introgression DH lines in collaboration with the USDA gene bank in Ames, and (iii) transfer knowledge to other species.
