Abstract: Provided are isolated cDNAs comprising a nucleotide sequence having at least 90% identity to SEQ ID NO: 33, SEQ ID NO: 37, SEQ ID NO: 52 or SEQ ID NO: 53. Also provided are expression cassettes; vectors; transgenic plant cells; plants, plant parts, and seeds; isolated polypeptides; amplicons and informative fragments of the presently disclosed nucleic acids; compositions that include amplification primer pairs; methods for producing plants that exhibit HI; methods for identifying the presence or absence of an allele associated with HI in a plant; methods for introgressing Haploid-inducing nucleotide sequences into plants; and methods for selecting parental plants predicted to produce progeny generations with plants that exhibit Haploid Induction trait.

Abstract: Provided are expression cassettes; vectors; transgenic plant cells; plants, plant parts, and seeds; isolated polypeptides; amplicons and informative fragments of the presently disclosed nucleic acids; compositions that include amplification primer pairs; methods for producing plants that exhibit haploid induction (HI); methods for identifying the presence or absence of an allele associated with HI in a plant; methods for introgressing Haploid-inducing nucleotide sequences into plants; and methods for selecting parental plants predicted to produce progeny generations with plants that exhibit Haploid Induction trait.

Abstract: Provided are isolated cDNAs. In some embodiments, the isolated cDNA are selected from the group consisting of: (a) a nucleic acid having at least 90% identity to SEQ ID NO: 33, SEQ ID NO: 37, SEQ ID NO: 52 or SEQ ID NO: 53, optionally wherein the percent identity is calculated over the entire length of SEQ ID NO: 33, SEQ ID NO: 37, SEQ ID NO: 52 or SEQ ID NO: 53; (b) a nucleic acid having at least 95% identity over nucleotides 91-1452 of SEQ ID NO: 33; (c) a nucleic acid that is the reverse complement of either of (a) or (b); and (d) a nucleic acid that encodes a polypeptide comprising an amino acid sequence that is at least 95% identical to SEQ ID NO: 54, or SEQ ID NO: 55, or SEQ ID NO: 56, or SEQ ID NO: 57 optionally wherein the percent identity is calculated over the entire length of SEQ ID NO: 54, or SEQ ID NO: 55, or SEQ ID NO: 56, or SEQ ID NO: 57.
