In a diploid grass, perennial ryegrass (Lolium perenne L.), many autotetraploid cultivars have been released and widely used in many cool temperate countries. In this study, competitive ability and cold tolerance, which seem to be important factors in determining geographical distribution and persistency of this species, were compared between six diploid… CONTINUE READING
