Although around the globe numerous studies have been conducted on the nutritional composition of blueberry/bilberry and its effect on human health, very little is known about the fruit in Bosnia and Herzegovina. This is the first report regarding the physical and chemical characteristics of the cultivated highbush blueberry and bilberry harvested in the same climatic conditions in Bosnia and Herzegovina. In this paper we present the physical (weight) and chemical (soluble solids content, total sugars, titratable acidity, pH, and total phenols) properties of the wild bilberry (Vaccinium myrtillus L.) and cultivated highbush-'Earliblue' , 'Bluegold' , 'Bluecrop' , 'Goldtraube'-blueberry (Vaccinium corymbosum L.). Among the highbush blueberry cultivars, 'Bluegold' (2.07-2.11 g) and 'Bluecrop' (2.08-2.11 g) had the highest weight. 'Bluecrop' had the highest soluble solids content (13.3-13.7 °Brix) and total sugars (9.73%-9.94%), but the lowest content of titratable acidity (0.70-0.72 g/100 g), which was highest in 'Goldtraube' (0.92-0.93 g/100 g). This cultivar also had the highest content of total phenols (289-309 mg gallic acid equivalent/100 g of fresh weight). In the case of wild bilberry, the following values were obtained: average weight 0.28-0.32 g, soluble solids content 11.1-11.3 °Brix, total sugars 7.23%-7.37%, titratable acidity 0.99%-1.02%, and total phenols 431-455 mg/100 g. Blueberry and wild bilberry also had a fairly uniform pH (3.2-3.6). All samples had a valuable composition and so it is advisory to expand their production in Bosnia and Herzegovina in order to increase their consumption.

The paper presents the results of the analysis of phenological and morphological characteristics of 3 hazelnut cultivars present in the production plantation in the north-western Bosnia and Herzegovina. The 'Rimski', 'Istarski dugi' and 'Tonda Gentile Romana' cultivars served as research material. Blooming time ranged from December to March. For all cultivars, the occurrence of dichogamy, precisely protandry, was observed. The longest flowering period of both male and female flowers was found in the 'Tonda Gentile Romana' cultivar. The 'Rimski' cultivar had the highest fruit weight (3.04 g). 'Tonda Gentile Romana' had the highest kernel weight (1.50 g). The highest kernel percentage (49%) was found in 'Istarski dugi'. The length of male catkins ranged from 21.73 cm to 29.76 cm. Statistically significant differences among cultivars were found for the following traits: the length of male catkins, the number of female flowers in glomeruli, and the number of nuts on a fruiting shoot. The 'Istarski' cultivar had the highest average length of male catkins (29.76) and the highest number of female flowers in the glomeruli (7.32). 'Tonda Gentile Romana' had the highest number of fruits (20.93) on the shoots. All three cultivars have proven to be good varieties in terms of phenological and morphological characteristics, so they can be recommended for intensive production of this nut crop.

The research included seven autochthonous apple varieties in the area of Tomislavgrad, Stipanjići locality, during 2018, which represent the natural wealth of our country. In seven autochthonous apple varieties: Petrovača bijela, Budimka, Ljutika-Divljaka, Ledarica, Bedrica, Ljepocvjetka-Cvjetača and Jonatanka, phenological characteristics were monitored and analyzed with morphological-pomological properties of fruits. The following phenological characteristics were monitored: flowering phenophases, germination of the first fruits, fruit growth, fruit ripening and full maturity. Five characteristics for the description of apple fruits were determined using the UPOV descriptor for apples (UPOV, 2003). The results of monitoring the morphological and pomological properties of fruits show that the lowest average fruit weight was in the variety of Cvjetača (58,38 g), while the highest average of fruit weight had variety Bedrica (140,59 g). In the result is evident that the lowest value of fruit width had variety Cvjetača (53,72 mm), and the highest had variety of Jonatanka (70,83 mm). The Cvjetača variety had the lowest average fruit lenght (47,24 mm), while the Bedrica variety had the highest (59,72 mm). The Budimka variety had the highest average stem length (2,73 cm), while the Divljak variety had the lowest average stem length (1,43 cm). The Jonatanka variety had the largest average cup concavity and was (1,28 mm), while the Petrovača bijela variety (0,41 mm) had the lowest average cup concavity. Based on the this research, the examined autochthonous apple varieties can be used a valuable genetic material in breeding programs, and can be used to create new varieties, as well as for propagation in commercial plantations.
