“…In a situation where maternal haploids are the end product, the inducer line is typically the pollen parent (Fehr 1984;R€ ober et al 2005). When paternal haploids represent the final product, the maternal or egg parent represents the inducer line, such as is seen with the indeterminate gametophyte system of maize (Kermicle 1969 (Kindiger and Singh 2011;Kindiger 2012). Tall fescue (2n = 6x = 42) represents the predominant, introduced perennial cool-season grass forage in the USA.…”

Within the Lolium‐Festuca genome complex there is a need for modern breeding approaches that can facilitate the rapid development of improved germplasm or cultivars. Traditional recurrent or mass‐selection methods for population or synthetic development are labor intensive and time consuming. The recent development of dihaploid (DH) inducer lines of annual ryegrass (Lolium perenne L. subsp. multiflorum (Lam.) Husnot [syn. Lolium multiflorum Lam.]) that exhibit genome loss when hybridized with tall fescue (Lolium arundinaceum (Schreb.) Darbysh. [syn. Festuca arundinacea Schreb.]) can provide an alternative breeding approach. Hybridizations between the inducer lines and tall fescue result in F1 hybrids that can lose either their ryegrass or tall fescue genomes. This behavior results in the occasional generation of both ryegrass and tall fescue DH lines through parthenogenic embryo formation within the F1 inflorescence.

Development of haploid and/or dihaploid methodologies for Lolium sp. is important to future improvement efforts as the genus includes the majority of the world's cool‐season annual and perennial turf and forage grass species. Microspore or anther culture haploid induction systems can result in the generation of either maternal or paternal haploids that can be effectively used to advance genetic gains through a breeding or selection program. The successful and traditional approach for the production of haploids and eventually dihaploids in Lolium sp. is most successful when microspore culture approaches are applied. Unfortunately, this approach is labor‐intensive, expensive and often restrictive to amendable genotypes. Within the Lolium‐Festuca genome complex, there is a need for modern breeding approaches that can facilitate the rapid development of haploids or dihaploids for the development of improved germplasm or cultivars. It has been suggested that an in vivo approach could facilitate further advances in Lolium sp. genetic studies, molecular breeding and superior cultivar development. The recent development of a two novel annual ryegrass (Lolium perenne L. subsp. multiflorum (Lam.) Husnot [syn. L. multiflorum Lam.]) line that when hybridized to tall fescue (Schedonorus arundinaceus (Schreb.) Dumort., nom. cons.) has been previously demonstrated. This research investigates and reports on the potential generation of haploids and/or dihaploids through this novel ryegrass when hybridized with L. multiflorum or L. perenne and production of the first invivo haploid/dihaploid Lolium sp. approach.
