The experiment was established at private apricot orchard near Cacak (Western Serbia) during 2010 and 2011. In the present study we wanted to determine the physicochemical attributes, phenolics content and antioxidant capacity of three new Serbian cultivars (‘Aleksandar’, ‘Biljana’, ‘Vera’) grafted on Myrobalan seedlings. Results indicated that physico-chemical attributes significantly varied among cultivars. Similarly, total phenolics and flavonoids content and antioxidant capacity significantly depend on the cultivars. Generally, new Serbian cultivars had better properties evaluated than control (‘Hungarian Best’), except stone weight, fruit firmness, moisture and total phenolics content. The highest values of total phenolics and flavonoids content were found in ‘Aleksandar’, whereas the highest antioxidant capacity was recorded in ‘Vera’. Finally, new Serbian cultivars could be recommended for planting in similar conditions and apricot growing programs.

Breeding of stone rootstock is very important problem for orcharding. In many countries of the world have been obtained a lot of new breeding material for sweet and sour cherries and plums. An analysis was conducted in Cacak (Western Serbia) in the 2006–2007 period to examine major morphological traits of the aerial part and root of suckers derived from mother bushes of three newly vegetative rootstocks for stone fruit species, particularly plum, peach and apricot trees. The newly breed rootstocks have been developed from autochthonous genetic material, their specific designations being: FA 2/53 (Prunus domestica L.), FA 5/7 (P. domestica L.) and FA 6/209 (P. cerasifera Ehrh.). The analysis of suckers of the new rootstocks included the investigation of morphological traits through the determination of: a) length of the aerial part, b) number of feathers on aerial part, c) number of roots, d) length of roots, and e) volume, weight and category of the roots. They developed branch roots and exhibited good length of the aerial part, a substantial number of roots and root dry weight. The FA 2/53 rootstock can be classified into low-vigour rootstocks, FA 5/7 into low to moderately vigorous ones (slightly more vigorous than the FA 2/53 rootstock) and FA 6/209 into moderately vigorous rootstock for stone fruits.

Fruit apricot dimensions, weight, size and shape are the most commonly measured pomological properties. The size and shape features of 13 apricot (Prunus armeniaca L.) cultivars and promising Serbian selections grown in Western Serbia were investigated using a multivariate analysis. The apricots promoted fruits wider than long in shape, except ‘Harcot’, ‘T 7’, ‘Précoce de Tyrinthe’, ‘Roksana’ and ‘Vera’, whereas all cultivars and selections are wider than thick. Most of cultivars and/or selections tend to round shape. Mean values for fruit and stone weight, flesh rate, geometric mean diameter, kernel weight, sphericity, aspect ratio, surface area and volume ranged from 37.09 to 81.60 g, 2.71 to 4.18 g, 91.93 to 96.46%, 41.76 to 65.08 mm, 0.60 to 1.17 g, 0.94 to 1.03, 95.04 to 108.09%, 55.13 to 133.77 cm2 and 38.31 to 145.10 cm3 , respectively. For the most of attributes evaluated, ‘Roksana’ had the highest values. A high correlation was found among some physical attributes. According to their 22 properties, the apricots grouped into five clusters. There was either relative independence or close correspondence among the evaluation indexes of apricot fruit quality. Principal components analysis showed that the first three principal components variance accumulation contribution rate amounted to 85.77%, which reflected most of the size and shape characteristics of apricots.

The study was conducted to determine the effects of Myrobalan rootstock and Blackthorn interstock on fruit physical and chemical traits of five apricot cultivars. The results showed that cultivars grafted on Myrobalan rootstock appear to induce a higher fruit mass when compared with the Blackthorn interstock. Blackthorn interstock showed a tendency to induce a higher soluble solids/titratable acidity ratio than Myrobalan. Values of soluble solids content, total sugars, titratable acidity and fruit firmness between Myrobalan rootstock and Blackthorn interstock were not significant. Regarding cultivars, the greatest fruit mass observed in Roxana in both treatments, and the lowest in Biljana on Myrobalan and in Vera on Blackthorn. The lowest soluble solids, total sugars and soluble solids/titratable acidity ratio were found in Roxana in both variants of grafting, whereas the greatest titratable acidity also observed in Roxana in both cases, respectively. Based on the results from this study, the fruits of Roxana can be recommended for fresh consumption, whereas fruits of the other cultivars can be recommended for processing.

A 3-year study was done to compare the blossoming and harvesting date, fruit physical and chemical composition of six nectarine cultivars grown with High Density Planting system under western Serbian conditions. A high variability among and within cultivars was found and significant differences were observed among them in all properties analyzed. Year-by-year variations were observed for blossoming and harvesting date, length of fruit growth, soluble solids content, fruit weight and fruit firmness. On the basis of evaluated data, the best fruit performance registered in ‘Caldesi 2000’ and ‘Syrio’ grown with HDP on heavy soil. Contrary, the poor fruit physico-chemical properties were observed in ‘Mayfire’, especially in ‘Nectared 4’. This evaluation may help to select a set of nectarine cultivars with better fruit quality attributes, which in our growing conditions might be indicated in ‘Caldesi 2000’, ‘Syrio’, somewhat ‘Weinberger’ and ‘Fantasia’.
