Selection for forage quality in tall fescue using a dihaploid generation approach

W

ithin the

Festuca-Lolium

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 annual ryegrass

Lolium multiflorum

Lam. subsp.

multiflorum

lines, that when hybridized by tall fescue (

Festuca arundinacea

Schreb. (syn.=

Lolium arundinaceum

(Schreb.) Darbysh.),

generate F1 hybrids capable of exhibiting genome loss of either the ryegrass tall fescue genome resulting in the recovery of both

ryegrass and tall fescue dihaploid (DH) lines. Gamete selection performed at the F1 generation was found to be effective and may

have application toward the selection of additional quantitative forage quality or agronomic attributes in tall fescue germplasm. The

described gamete selection strategy is applicable to tall fescue (

L. arundinaceum

) and may have applications across the

Lolium/Festuca

genus.

Biography

Bryan Kindiger has completed his PhD from the University of Missouri, Columbia and has been employed with the USDA-ARS for 23 years. He is the lead

Researcher for the development of cool-season grass forages at the Grazinglands Research Laboratory. He is presently working on a dihaploid inducement

approach for representatives of the

Lolium

and Festuca

genus.
