Abstract:
Seedlots of meadow fescue (Festuca pratensis Huds.), timothy (Phleum pratense L.) and perennial ryegrass (Lolium perenne L.) were increased for 2-4 consecutive generations at 1 location in Germany and 3 locations in the USA. The population structure and forage yields of the original seed and advanced generations were investigated at Weihenstephan, Germany. All meadow fescue progenies were significantly taller and earlier and made better regrowth than the original seed. American lots and the corresponding German populations did not significantly differ in these characters. In timothy, variation of plant characteristics among locations and generations was negligible. In perennial ryegrass, most progenies were significantly more vigorous in spring, earlier and taller than the original lot. American lots from lower latitudes were taller and earlier. The 4th subsequent generation from the most southerly location, Shafter, California [USA], headed 6 days earlier and grew 11 cm taller than the original lot. Percentage of seedling fluorescence of samples from the USA did not differ from the corresponding German progenies. There was no detrimental effect on a dry matter forage yield due to seed multiplication in the USA.
