Apple accessions, currently maintained within the two main ex situ collections in Bosnia and Herzegovina (B&H), have previously been genotyped using microsatellite markers. The obtained molecular ...data provided insight into mislabeled accessions and redundancies, as well as the overall genetic structure of the germplasm. The available dataset enabled the creation of a core collection consisting of 52 accessions. The reliability and usefulness of microsatellites has made this low-density marker system a norm in studies on apple germplasm. However, the increased access to medium- and high-density SNP arrays, developed specifically for apples, has opened new avenues of research into apple genetic resources. In this study, 45 apple genotypes consisting of 33 diploid core collection accessions from B&H and 12 international reference cultivars were genotyped using an Axiom® Apple 480 K SNP array in order to examine their genetic relationships, population structure and diversity, as well as to compare the obtained results with those calculated on previously reported SSR profiles. The SNPs displayed a better ability to differentiate apple accessions based on their origin, as well as to cluster them according to their pedigree. Calculating identity by descent revealed 16 pairings with first-degree relationships and uncovered the introgression of ‘Delicious’ and ‘Golden Delicious’ into the core collection.
This study was conducted with the aim of developing fruit spirits by utilizing old (autochthonous) apple and pear cultivars that can be attractive to both consumers and producers. Consumers of ...spirits could enjoy the unique flavor, and producers could gain an opportunity for brand development. In total, eight old apple cultivars (Sarija, Žuja, Samoniklica, Prijedorska zelenika, Bobovec, Masnjača, Lijepocvjetka, and Šarenika) and three pear cultivars (Budaljača, Krakača, and Kalićanka) from Bosnia and Herzegovina were used for the spirits production and for characterizing the flavor of distillates. Golden Delicious was used as a representative of commercial apple cultivar. The aroma profile was conducted through the identification of minor volatile organic compounds (VOCs) and the sensory perception of spirits. Analysis of the VOCs was performed by gas chromatography mass spectroscopy (GC/MS) techniques after enrichment via solid-phase microextraction (SPME). Sensory evaluation was performed by 12 trained panelists. Overall, 35 minor volatile compounds were found in spirits: 13 esters, 7 alcohols, 6 acids, 5 terpenes, and 4 aldehydes. Significant differences were detected in the distribution and quantity of the VOCs, which were fruit cultivar-dependent. Spirits made from Šarenika apple cultivar showed the largest amount of all acids, especially short- and medium-chain fatty acids; however, this richness was not correlated with pleasant sensory attributes. Spirits obtained from Prijedorska zelenika and Masnjača apple cultivars had the best sensory attributes. Budeljača and Krakača pears are promising cultivars as flavoring in spirits production.
In order to assess the genetic purity of common buckwheat variety ‘Darja’ which is the most commonly produced variety of this crop in Bosnia and Herzegovina, 10 SSR markers have been used. Five ...samples have been collected from different production regions in B&H (Breza, Nisici Plateau, Ustikolina, Bihac and Bosanska Krupa) and compared to the reference ‘Darja’ sample obtained from an ex situ seed collection from Slovenia. Seven out of ten primer pairs used managed to amplify SSR alleles. Analyses of molecular variance (AMOVA) showed a significant differentiation between the reference and all analyzed ‘Darja’ samples. Furthermore, the factorial correspondence analysis revealed a clear differentiation between the reference and ‘Darja’ samples from the most known production regions of common buckwheat in B&H clustering four out of five analyzed samples very close together. The most divergent one among the analyzed samples was the one from Ustikolina. Genetic purity of varieties of all of cross pollinated species produced in Bosnia and Herzegovina is questionable due to the general use of farm-saved seeds.
Raspberry cultivars are clonally propagated and therefore all plants belonging to a single cultivar represent the same genotype. Cultivar integrity of raspberry plantlings placed on the market in ...Bosnia and Herzegovina (B&H) is based on examining of morphological traits, which is not a reliable tool for genetic identification. In this study plantlings declared as cultivar ‘Polana’ were genotyped using seven microsatellites, in order to gain preliminary insight into the genetic integrity of raspberry plantlings marketed in B&H. Plant tissue (leaves) from 10 raspberry plants were randomly sampled from a batch of plantlings sold by major fruit nursery in Bosnia and Herzegovina. Along with these samples, four reference cultivars with confirmed identity (‘Polka’, ‘Autumn Bliss’, ‘Heritage’ and ‘Polana’) were also included in the study. Seven primer pairs amplified 31 alleles, or on average 4.4 alleles per locus. UPGMA cluster analysis, based on the Jaccard similarity coefficient, revealed that among the ten samples declared as ‘Polana’ plantlings only five were genetically identical to any of the other samples. The cluster analyses also exposed that none of the ten samples declared as ‘Polana’ seedlings were in fact identical or even closely related to the ‘Polana’ reference cultivar or any of the other reference cultivars. These findings clearly show that the genetic identity of primocane raspberry plantlings , currently sold in Bosnia and Herzegovina, needs to be tested using objective and reliable methods rather than simple morphologic observation.
