Opis:
The mode of inheritance and the degree of phenotypic correlation between some more important agronomic traits in two offsprings obtained by direct and reciprocal crossing of cultivars ‘Smederevka’ and ‘Gewurztraminer’ were investigated in this study. In 62 genotypes from direct crossing (Smederevka × Gewurztraminer) and 66 genotypes from reciprocal crossing (Gewurztraminer × Smederevka), the traits evaluated were as follows: time of bud burst, flowering time, ripening time, bunch weight, berry weight, grape yield, sugar content of must and total acidity of must. The genotypes of F₁ generation for the investigated traits were arranged into a number of categories by the OIV method. In both crossing combinations (direct and reciprocal) for most traits, the same mode of inheritance (partial dominance, dominance or heterosis) was determined. Differences in the mode of inheritance, depending on whether the parental varieties were used as a father or mother, were found only for ripening time (partial dominance and intermediate inheritance). The prevailing mode of inheritance established for most of studied traits, regardless of the crossing method, was negative heterosis. From all examined traits, a significant influence of maternal effect was determined for the inheritance of flowering time and ripening time. In both crossing combinations, statistically significant phenotypic correlations were found between some studied traits.

Opis:
Morpho-anatomical characteristics of Vaccinium myrtillus, V. uliginosum and V. vitis-idaea leaves from several sites of the Central Balkans were examined. The aim of this study was to investigate for the first time morpho-anatomical leaf traits of these species in the studied populations and to identify traits that follow a specific trend along the gradients of climate factors. Leaf traits that discriminate Vaccinium species were as follows: depth of the adaxial cuticule (AdC), thickness of the palisade tissue (PT), thickness of the spongy tissue (ST), height of the abaxial epidermal cells (AbE), height of the abaxial cuticule (AbC) and leaf thickness (LT). Populations of V. myrtillus were characterized by the smallest, and populations of V. vitis-idaea by the highest values for AdC, PT, ST, AbE and LT. Additionally, AbC was significantly larger for V. uliginosum in comparison to two other species. On the basis of morpho-anatomical traits, intraspecific variability of the studied species was explored by Principal Component Analysis (PCA), Cluster Analysis (CA) and Analysis of Variance (ANOVA). CA based on 10 morpho-anatomical traits showed that populations of V. myrtillus and V. uliginosum that grew at lower altitudes (characterized by higher mean annual temperature) are more similar to each other. Especially V. myrtillus was responsive to the elevational gradient and exhibited the highest plasticity in morpho-anatomical leaf traits. Populations of V. vitis-idaea had a different pattern of differentiation along the elevational gradient. CA showed that the populations at the lowest and at the highest altitudes were more similar according to the morpho-anatomical leaf traits, meaning that evergreen leaves were more resistant to environmental conditions.
