Abstract: A method for producing haploid Lolium plants may start with providing a Lolium multiflorum inducer line, the L. multiflorum inducer line having the ability to induce mitotic genome instability and haploid sectoring when hybridized as a maternal parent with a Lolium sp. paternal parent, such as previously disclosed lines IL1 and IL2. The inducer line may then be crossed with a Lolium sp. to generate F1 plants, and the F1 plants may be self-fertilized so as to recover seed from the selfed plant. The recovered seed may then be planted to generate one or more F2 plants, and at least one of the F2 plants may be a haploid Lolium plant.

Abstract: Dihaploid recoveries of Schendonorus meadow fescue and festulolium may be created using the method disclosed herein. The method includes crossing a ryegrass (Lolium multiflorum) inducer line (IL) with individuals from a meadow fescue or festulolium cultivar or population. Such a cross can create a variety of resulting individual plants, including dihaploid recoveries. Some of the dihaploid recoveries can also be rhizomatous even when the parental meadow fescue or festulolium plant did not display a rhizomatous trait.

Abstract: The tall fescue DH66OP Accession No. PI 690020 represents a genetic stock possessing an L. multiflorum cytoplasm that can enhance or induce rhizome formation across various genotypes. DH66OP may allow for the transfer the L. multiflorum cytoplasm to additional tall fescue genotypes for the recovery of genotypes expressing rhizomes.

Abstract: Dihaploid homozygous Fescue species may be produced by interspecific hybridization of Fescue with novel ryegrass, Lolium multiflorum, lines, that induce genome loss. Plants that are dihaploid homozygous Lolium and amphidiploids are also produced.

Abstract: Apomictic maize/Tripsacum hybrids having a ratio of maize chromosomes: Tripsacum chromosomes of at least 30:9 have been developed. These hybrids are useful for introgressing diplosporous apomictic reproduction into a maize background toward the ultimate goal of establishing immortalized commercial lines of apomictic maize having stably inherited characteristics without the need for continuously producing hybrid seed by repeated crossings of selected parental lines.DNA primers for use in assaying maize/Tripsacum hybrids for apomictic reproduction behavior are provided.
