Evaluation of Turf-type Interspecific Hybrids of Meadow Fescue with Perennial Ryegrass for Improved Stress Tolerance

Original language description

Broadening the genetic pool of crop species by wide hybridization is an established practice in plant breeding. Festuca x Lolium hybrids (Festulolium [FL]) are already established as commercial forage grasses around the world. By recurrent selection fordrought and heat tolerance we developed turf-type populations of FL with increased stress tolerance. This improvement appeared associated with the presence of an introgression of meadow fescue [Festuca pratensis (Huds.) P. Beauv.] chromatin on chromosome3 of perennial ryegrass (Lolium perenne L.). To determine if deeper and more extensive root characteristics were responsible for increased stress tolerance, a greenhouse study was conducted on FL both with and without the introgression, parental controls, and tall fescue (F. arundinacea Schreb.). In two experiments in sand-filled tubes, meadow fescue (MF) produced the deepest roots, most root biomass, and highest root: shoot ratio; FL and perennial ryegrass (PR) were intermediate while
