Abstract
An assay of the number of incompatibility alleles in an experimental c ultivar of Lolium perenne found 17 S- and 13 Z-alleles in samples of 4 0 and 43 plants examined, respectively, which yielded estimates of 26 S- and 18 Z-alleles in the population. This cultivar was founded, howe ver, on only five plants that between them could have contained no mor e than 10 alleles at each locus. It is suggested that the additional a lleles originated by migration of pollen from neighbouring populations of ryegrass during seed-multiplication rather than from mutation.
