Three diploid Trifolium (Fabaceae) species, T. campestre, T.fragiferum and T. montanum, were electrophoretically assayed to elucidate the range and organization of genetic variation in relation to the mating system, reproduction mode and longevity of the species. T. campestre is an annual self-pollinated species. T.fragiferum and T. montanum are cross-pollinated perennials. The former species reproduces both sexually and vegetatively, whereas the latter relies solely on sexual reproduction. Several populations of each species collected throughout Poland were surveyed for 15 enzymes. The measures of variation included: proportion of polymorphic loci per population, average number of alleles per locus, average gene diversity (He) and genetic distance (D). To describe the organization of diversity in each species, total genetic variation per locus (Ht) was calculated and partitioned into intra-(Hs) and inter-(Dst) populational components. Both cross-pollinated species had more polymorphic loci, higher numbers of alleles per locus and higher level of diversity than self-pollinated T. campestre. Most of genetic variation of the latter species was allocated among populations unlike in T.fragiferum and T. montanum.
