1. A method of breeding maize for spontaneous haploid genome doubling comprising:
obtaining a source plant with a spontaneous haploid genome doubling locus comprising a variant BUBR1 gene;
selecting said plant for use as a parent plant;
crossing said parent plant with a second plant to produce a population of progeny plants; and
genotyping one or more progeny plants with one or more nucleic acid markers within a chromosomal interval defined by and including the terminal markers 504_21 and umc2302 on maize chromosome 5 to determine if the progeny plant has the spontaneous haploid genome doubling locus.
