Germplasm of Bosnia and Herzegovina

• The territory of Bosnia and Herzegovina (B&H) has been historically exposed to the influences of different civilizations.

• In B&H, through spontaneous or planned hybridization and selection, introduced germplasm participated in the creation of new autochthonous varieties .

Identification of Germplasm by molecular markers

• The studies were performed on Malus germplasm and (Gaši et al., 2010), Pyrus germplasm (Gaši et al., 2013) using SSR (Simple sequence repeats) markers.

• A total of 39 accessions of apple, 24 traditional B&H cultivars and 15 modern international cultivars were investigated using 10 SSR (simple sequence repeats) markers and 23 morphologic characteristics.

• This study showed that traditional apple cultivars from B&H, have a high number of unique alleles, and that there is no correlation between the molecular and morphologic set (Gaši et al., 2010).

• Pear germplasm were also analyzed.

• Using 13 microsatellite markers 64 pear accessions were analyzed, 27 traditional B&H cultivars and 9 international reference cultivars.

• Traditional B&H pear accessions differentiated genetically from the international pear cultivars and genetic structure revealed that most international cultivars grouped in a single reconstructed panmictic population (Gaši et al., 2013).

• Grapevine cultivars were also analyzed with AFLP (Amplified fragment length polymorphism) and SSR markers. Because unknown origin, cultivar "Žilavka" was analyzed with SSR markers in order to obtain a standard "Žilavka" genotype.

• Also, AFLP markers were used to investigate the genetic basis of variability within the cultivar (Tomić et al., 2010).

• A set of B&H grapevine cultivars was analyzed by SSR markers in order to assess true cultivar identity, genetic relationships and to detect the level of genetic diversity.

• Fifty-one collected grapevine cultivars of Bosnia and Herzegovina were analyzed by 22 microsatellite markers. Twenty-five unique fingerprints representing 23 cultivars and 2 unnamed genotypes were found.

• The results of the study will be used for establishing a non-redundant grapevine germplasm collection (Tomić et al., 2012).

• RAPD (Randomly amplified polymorphic markers) was applied for initial molecular analysis of ray (Secale cereale L.) accessions in the Gene Bank of Republic of Srpska.

• Comparison of five ray accessions showed that in the Gene Bank exist duplicate ray accession (Kajkut et al., 2012).

• RAPD markers are also used for preliminary identification of pear germplasm in order to eliminate duplicate accessions in Field Gene Bank.

• From eleven analized pear accessions, five of them had same coefficien of genetic similartiy. That were accessions from Lubenicarka group.
