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

Popis výsledku v původním jazyce

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
