Chapter synopsis: Current European barley breeding programs predominately rely on doubled haploid (DH) technology delivering several essential advantages, such as accelerated development of homozygous genotypes, early recognition of major recessive traits, enabling to select faster and much more robust, and facilitation of maintenance breeding starting directly from homozygotes. This chapter gives a general overview of the different methods involved in doubled haploid technology, focusing on their relevance the application in practical barley breeding programs. The chapter examines wide hybridization, anther culture (AC), isolated microspore culture (MC) and parthenogenesis.
