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.
