“…Following the increase of the IL1 and IL2 lines, the ryegrass × tall fescue hybridizations were repeated in 2006 utilizing the IL lines as the maternal parent and using the tall fescue cv ‘Nanyro’ (Kindiger et al . ) as the paternal parent within a hoop house. Hand pollinations were performed by applying a bulk of tall fescue pollen to the stigma of sterile or partially sterile IL1 or IL2 individuals.…”

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.

“…Clade 6 including five cultivars could be divided into sub-clades with three and one cultivar respectively. Here Forager and Nanryo sharing one of the common parent germplasm Fawn resulted to a firm genetic relationship with the high bootstrap values [49, 50]. Additionally, Barvetia and Martin formed a sub-clade with a middle bootstrap value of 42 %, but this could not correspond to their pedigree information, since Barvetia was developed in Netherland and Martin was developed in Missouri university of USA [8, 47, 51].…”

BackgroundGenetic diversity of 19 forage-type and 2 turf-type cultivars of tall fescue (Festuca arundinacea Schreb.) was revealed using SSR markers in an attempt to explore the genetic relationships among them, and examine potential use of SSR markers to identify cultivars by bulked samples.ResultsA total of 227 clear band was scored with 14 SSR primers and out of which 201 (88.6 %) were found polymorphic. The percentage of polymorphic bands (PPB) per primer pair varied from 62.5 to 100 % with an average of 86.9 %. The polymorphism information content (PIC) value ranged from 0.116 to 0.347 with an average of 0.257 and the highest PIC value (0.347) was noticed for primer NFA040 followed by NFA113 (0.346) whereas the highest discriminating power (D) of 1 was shown in NFA037 and LMgSSR02-01C. A Neighbor-joining dendrogram and the principal component analysis identified six major clusters and grouped the cultivars in agreement with their breeding histories. STRUCTURE analysis divided these cultivars into 3 sub-clades which correspond to distance based groupings.ConclusionThese findings indicates that SSR markers by bulking strategy are a useful tool to measure genetic diversity among tall fescue cultivars and could be used to supplement morphological data for plant variety protection.

Within the Festuca-Lolium genome complex there is a need for the rapid development of improved germplasm resources. Traditional recurrent selection methods for population or synthetic development are labor intensive and time consuming. One objective of our research is to identify novel genetic methods that will enhance traditional breeding methods and facilitate the development of improved Lolium spp. germplasm resources. IL1 (Reg. No. GS-9, PI 660129) is a wide-based, diploid (2n = 2x = 14), early maturing, annual ryegrass [Lolium perenne L. subsp. multifl orum (Lam.) Husnot (syn. Lolium multifl orum Lam.)] genetic stock that has the ability to induce genome or chromosome loss when hybridized with other Lolium species. IL1 was developed from a population segregating for a low level of pollen sterility. IL1 has been identifi ed to produce dihaploid lines following interspecifi c Lolium × Festuca hybridizations either through chimeral sectors or through rare seed development. The hybrids are capable of producing viable seed via genome loss and a infrequency parthenogenic response. Utilizing these materials with a complementary breeding approach may provide for the development of new and superior Lolium spp. cultivars. The release of this material will be of value to researchers of Lolium spp. breeding programs focused on developing improved germplasm.
