Although an annual, ranchers in the southeast U.S. depend on it for its reseeding ability, resulting in "volunteer" stands of annual ryegrass from year to year once the seed bank is established. 25% nonrecombinants, 50% single recombinants and 25% double recombinants (Kearsey and Pooni, 1996). To test these hypotheses, Lolium perenne L. plants were grown from seeds in a growth chamber in pots containing a silica sand/soil mixture for 9 weeks with and without inoculation with Glomus intraradices (Schenck and Smith). The ewes that grazed L in P1 grazed F in P2 and vice versa. Join With a snow cover, ryegrass can tolerate even lower temperatures. When combined with diploid perennial ryegrass a perfect overseeding mix is obtained. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world. Perennial ryegrass (Lolium perenne L.) is a cool-season, bunch type grass that performs well in a wide variety of soil conditions but thrives in dark, rich soils with a pH between 5 and 8 in regions with mild climates (Paterson, 2002; USDA, 2002). The four major agricultural species within the Lolium‐Festuca complex, L. multiflorum (Italian ryegrass), L. perenne (perennial ryegrass), F. pratensis (meadow fescue), and F. arundinacea (tall fescue), are the most important sources of forage grass in temperate regions of the world.

It prefers milder climates, but tolerates temperatures down to minus 16 to 18°C without a snow cover. Generally, L. perenne requires vernalization for flowering but, since it is an obligate out-crosser, the level of genetic variation within a population can be significant. multiflorum Italian ryegrass Lolium perenne ssp.
