摘要：

An assay of the number of incompatibility alleles in an experimental cultivar of Lolium perenne found 17 S- and 13 Z-alleles in samples of 40 and 43 plants examined, respectively, which yielded estimates of 26 S- and 18 Z-alleles in the population. This cultivar was founded, however, on only five plants that between them could have contained no more than 10 alleles at each locus. It is suggested that the additional alleles originated by migration of pollen from neighbouring populations of ryegrass during seed-multiplication rather than from mutation.
