Abstract
The microsatellite markers are routinely used to investigate the genetic structure of natural populations. The mi-crosatellite polymorphisms are important for estimation diversity among varieties and for evaluation of the efficiency of microsatellite for establishing varieties relationships. The locus LECH13 was tested in six tomato varieties in order to evaluate its usefulness in the genetic differentiation among six morphologically different tomato varieties. The fragment analyses were performed using the Applied Biosystems DNA analyzer. The number of detected alleles for the microsat-ellites locus LECH13 was four in researched tomato varieties (134-136-138-146 bp). The allele138 bp was noticed only in Lycopersicon esculentum subsp. spontaneumvar. racemigerum. The average PIC value for the locus LECH13 was 0.3677 and it belongs to the group of modest informative markers. The present study showed that the locus LECH13 could be used in the genetic differentiation of tomato varieties, but in combination with other polymorphic microsatel-lite loci.
