Abstract:Using parthenogenesis inducer as male parent breeding maize inbred lines and by chromosome doubling can provide stable pure line quickly, as well as, shorten time of inbred lines breeding, speed up the breeding process and improve the efficiency of breeding. What reviewed in this article was a research progress in the mechanism of parthenogenesis haploid induction and chromosome doubling on maize, aimed to provide theoretical basis of maize haploid.
