Genetic relationship among autochthonous grapevine cultivars in Bosnia and Herzegovina

Grapevine growing area of Bosnia and Herzegovina is limited by surface, but in spite of this fact, there is a great number of autochthonous varieties. A small number of them have a greater commercial significance, while most of them are grown at a small scale. However, their genetic inter-relationships are presently unknown. The aim of this study was to genotype 26 accessions of native grapevine varieties from Bosnia and Herzegovina and to determine the number and frequency of alleles within this population. This should put more light on level of genetic diversity among studied accessions, as well as determine possible synonyms and homonyms. Genetic profile of each variety was produced with SSR markers at nine loci. On the basis of obtained results coefficient of genetic similarity was computed. The mean number of alleles per locus was 7, 33 and observed heterozygosity over all loci was 0, 77. Five clusters of identical genotypes were found ; some of them were expected, and some were not. Synonyms and homonyms were also found within the analyzed accessions. The coefficient of genetic similarity shows that there is a significant level of genetic distance and diversity among the tested varieties. This fact suggests that the grapevine varieties from Bosnia and Herzegovina may have different genetic and geographical origins. To further elaborate this, genetic relationship of grapevine varieties from Bosnia and Herzegovina and varieties from neighboring and distant areas, should be analyzed.
