Bosnia and Herzegovina (BIH) pear germplasm in the ex situ field collection at the University of Banja Luka was characterised with simple sequence repeat (SSR) markers in order to reveal redundancies, determine genetic diversity and confirm uniqueness. European pear (Pyrus communis L.) 67 accessions of the BIH collection and 7 reference cultivars of the ex situ collection at SLU in Balsgård, Sweden were analysed using a set of 10 SSR markers. All markers resulted in good amplification and easy scoring of marker alleles One-third of accessions appeared to be triploid. A total of 112 alleles were amplified in unique diploid genotypes with on average 11.2 alleles per marker. Mean observed heterozygosity (Ho) was 0.72, mean expected heterozygosity (He) – 0.80 and mean Shannon index (I) – 1.96. Inbreeding coefficient (FIT) for diploid accessions ranged from −0.06 to 0.28 (mean 0.02) and Wright’s inbreeding coefficient (FIS) – from −0.27 to 0.17 (mean −0.03). In the BIH pear collection, mean value of genetic differentiation (FST) between the reference cultivars and pear accessions was 0.05. Principal coordinate analysis (PCoA) divided the 74 pear accessions into three groups. The first group consisted of diploid, reference and possible triploid pear accessions, while the second and third groups contained only BIH possible triploid accessions. Overall, the results revealed high levels of polymorphism and uniqueness, indicating that BIH pear germplasm represents very diverse and valuable material for future breeding programmes.

This study aims to do a morphological and biochemical characterization of selected wild hop populations from the Banja Luka region, as plant material with potential value for introduction into plant selection. Female inflorescences (cones) from seven populations (DKH3, DKH5, DKH6, DKH8, DKH9, DKH10, and DKH11) were sampled in 2018 and 2019. Hop cones were collected in October 2018 and 2019 for morphological characterization, when 50 cones per population were analyzed, and also the cones were collected in mid-September in 2019 for biochemical characterization. Morphological parameters were carried out for: cone length (cm), number of nodes per cone spindle, cone density, and number of seeds per cone, all important agronomic characters in hop production. Also, 27 components of essential oil and 6 components of hop resins were analyzed. Statistical analysis of morphological characteristics was performed by factorial analysis of variance (year × population), and the significance of individual differences was determined by LSD test. The grouping of examined hop populations according to the manifested morphological characteristics was performed by cluster analysis. Statistical analysis for biochemical characteristics was performed by analysis of variance, and the significance of the differences was tested by Tukey’s statistical test. In order to determine similarities between different population multivariant statistical method Principal component analysis (PCA) was applied. According to morphological and biochemical analysis, DKH6 hop population is singled out as the most valuable for hop breeding.

Abstract Bosnia and Herzegovina (BiH) for many centuries has been a crossroad of various civilizations and religions, which made BiH’s kitchen one of the richest in Europe, even in the world. Food in BiH is rather fatty and delicious rather than healthy and light. It can be considered a food for real gourmands. This chapter presents the 15 most popular BiH foods: Herzegovinian cheese in a sack, Vlasic’s/Travnik’s cheese, Livno’s cheese, Romanija’s kajmak, Bosnian kebabs, Roasted lamb on a spit, Meat baked in the sac, Sudžuka, Cicvara, Bosnian pies, Bosnian pot, Japrak, Poljak bean soup, Herzegovinian sage honey, and Plum jam/bestilj. All these dishes produced with locally grown raw materials and local know-how fulfill the conditions to be certified with a geographical indication mark.

The paper presents the theoretical foundations in the field of analysis of the quality of the internal environment, ways to achieve thermal comfort, much has been said about the conditions for achieving adequate quality of the internal environment IEQ, as well as the principles of measuring IEQ parameters. Through four studies, the measurement of parameters for determining the thermal comfort in the indoor environment, as well as the impact of CO2 on IEQ and indoor air quality IAQ, ie a comprehensive analysis of IEQ was performed.
