A method of developing hexaploid (2n=6x=42) and octoploid (2n=8x=56) turf-type perennial ryegrass (Lolium perenne L.) and Festulolium [(American Ryegrass), x Festulolium loliaceum (Huds.) P. Fourn. (Festuca pratensis Huds. x Lolium perenne)], and their hybrids with Tall Fescue (Festuca arundinacea Schreb.) including germplasm, cultivars and seed used to produce the grass are provided. These grasses are useful as an improved turfgrass on golf courses, athletic fields and other areas using seeded turfgrasses. The grasses will provide a green improved winter performance and drought tolerance.

The present invention relates to non-transgenic and transgenic plants, preferably crop plants, comprising a mutation causing an alteration of the amino acid sequence in the CATD domain of the centromere histone H3 (CENH3), preferably within the loop1 or the 2-helix of the CATD domain, which have the biological activity of a haploid inducer. Further, the present invention provides methods of generating the plants of the present invention and haploid and double haploid plants obtainable by crossing the plants of the present invention with wildtype plants as well as methods of facilitating cytoplasm exchange.

The presently disclosed subject matter relates to using a haploid inducing line (whether existing or created) and transforming the haploid line so that it encodes cellular machinery capable of editing genes. The transformed haploid inducing line is used as a parent in a cross between two plants. During pollination, the parental gametes fuse to form an embryo; and the gene editing machinery is also delivered to the embryo at this time. During embryonic development, one set of parental chromosomes are lost, and the gene editing machinery operates on the remaining set of chromosomes. Thus, at least one haploid progeny with edited genes is produced from the cross.
