Abstract
Chromosome elimination resulting in haploids is achieved by rapid loss of chromosomes from one parent during zygote stage, and is an important procedure to produce doubled haploid (DH) lines in plants. During crosses between an emasculated wheat (Triticum aestivum L.) and a maize (Zea mays L.) as pollen donor, the complete loss of maize chromosomes results in wheat haploid embryos. Through embryo rescue and chromosome doubling process, pure lines with stable traits can be quickly obtained. We here term it as the maize-obligated wheat doubled haploids (mowDH). Although this technology is not new, it remains a practical approach to date. In order to optimize and improve this technology, and to achieve its maximum potential in the winter wheat area of China, this paper reviews the previous and on-going research, proposes a technical scheme for production of wheat DH lines via the maize pollen induction, and presents outlooks on DH research and its application in wheat breeding.
