Popis: In Silene pratensis three loci (g, gl and fg) control the glycosylation of isovitexin. Three alleles are known for both the g-locus (g, g G and g X ) and the gl-locus (gl, gl A and gl R ); for the fg-locus there are only two alleles (fg and Fg). The distribution of these alleles over 285 European populations of S. pratensis has been investigated. It was concluded that there are three different chemical races within S. pratensis in Europe. The first race contains the populations in western and southern Europe and displays high frequencies of g G , gl and fg. The frequencies of g G and gl R are very high in the second chemical race, which can be found in the USSR, Scandinavia and eastern Poland. The third chemical race occurs in central Europe and in this race the frequencies of both g and gl R are high, Fg has low to moderate frequencies in the second and third groups. The alleles gl A and g X are seldom found in S. pratensis, but are present in the closely related S. dioica. They do occur with low frequencies in some populations of S. pratensis, possibly as a result of hybridization with S. dioica.
