摘　　要：Nine diploid cultivars of Italian ryegrass （Lolium multiflorum Lain.） from France （Fortyl, Vertyl and Jericho）, Germany （Ligrande）, United Kingdom （Aber Epic and Aber Mario）, Denmark （Cordelia）, Netherlands （Alamo） and Poland （Tur） were tested with horizontal gel electrophoresis according to one locus （with four alleles） of the PGI enzyme system. One of them, named P4 is typical for the species, therefore can serve as a good marker for hybrids identification. Each cultivar was characterized by frequencies of different phenotypes. They were highly polymorphic （Pg = 0.58 - 0.78） and showed differences in heterozygosity level. The variability within populations （GST = 0.055） was higher than among populations （DST = 0.032）.
