This paper aims at determining the genotype x environment interactions of seed yield and quality components of NS soybean cultivars under different agroecological conditions. Field trials were conducted in Serbia, during three years (2009-2011). Six soybean genotypes, belonging to different maturity groups were used (MG): Valjevka, Galina, Afrodita (0 MG), Sava, Victoria (I MG) and Trijumf (II MG). The effect of genotype (G), environment (E) and GxE interactions on yield, protein content and oil content were found to be significant (P<0.05, P<0.01). During 2010 and 2011, significantly higher grain yield per area unit were achieved as compared to 2009. The highest stability of protein content in the whole tested period was found in genotype Galina. The highest seed yield and oil content were obtained by genotype Valjevka. Genotype Galina showed high stability and good performance in all years for seed yield and protein content. Soybean yield was positively significantly correlated with precipitation (r=0.48*) and negatively significantly correlated with temperatures (r=0.52*). Oil content was negatively highly significantly correlated with precipitation (r=0.83**) and positively highly significantly correlated with temperatures (r=0.81**). This study can represent the basis for further soybean breeding. © 2015, National Agricultural Research and Development Institute Fundulea. All rights reserved. Source

The influence of cattle manure, complex NPK (15:15:15) and calcium ammonium nitrate (CAN) mineral fertilisers and natural zeolite commercially named "Agrozel" on tree growth, productivity, fruit physico-chemical features and leaf nutritional status of four apricot cultivars was studied under acidic soil conditions in Western Serbia. Tree growth and yield performances were increased by CAN and NPK applications in general, whereas manure promoted the highest fruit weight. All fertilisers, except NPK promoted flesh firmness. Application of NPK improved primary fruit metabolites (soluble solids and total sugars content and titratable acidity), whereas Agrozel induced the highest levels of secondary metabolites [total phenolic content (TPC), total flavonoid content (TFC) and total antioxidant capacity (TAC)]. The highest tree vigor and the lowest productivity were observed in 'Biljana', while 'Harcot' had low tree vigor and high productivity. The largest fruits and highest flesh firmness were observed in 'Vera' and 'Biljana', respectively. Fruits of 'Aleksandar' are rich source in soluble solids content and TFC, 'Biljana' in total sugars, 'Vera' also in total sugars and TAC, while 'Harcot' had the highest levels of titratable acidity and TPC. Fertiliser treatments positively affected leaf macro- and micronutrients content, except leaf N and K at 120 days after full bloom (DAFB). All fertilisers induced excessive leaf P content, and deficiency of other nutrients in most cases. Leaf K and Mn contents, partially N and Cu, were not consistent. The highest imbalances and better balances among macronutrients were found when trees of 'Vera' and 'Harcot' fertilized with manure, respectively, whereas these characteristics among micronutrients were observed when trees of 'Aleksandar' and 'Biljana' fertilized with CAN, respectively. Leaf of 'Harcot' showed better balance values among macronutrients, and 'Biljana' among micronutrients. © 2013 Elsevier B.V. Source

The aim of this research was to determine variability and correlations between yield, protein content and oil content in soybean cultivars. The research was carried out on ten NS soybean cultivars in 2008, 2009 and 2010. All of the analysed traits significantly varied depending on cultivar and year. The highest yield in the analysed period was found in cultivar Proteinka (4,947 kg ha-1) which was significantly higher than that of cultivars Becejka, Tara, Afrodita and Diva. The highest average yield in 2010 was found in cultivars Irina (5,590 kg ha-1) and Bečejka (5,340 kg ha-1). The highest protein content was found in cultivars Afrodita and Galina, while the highest oil content was found in cultivars Alisa, Valjevka and Alisa. Significantly higher yield were obtained in 2010, while significantly higher protein and oil content was recorded in 2008. Yield was insignificantly positively correlated with oil content both in 2008, 2009 and 2010 (0.06, 0.31 and 0.17, respectively), and negatively but not significantly correlated with protein content (-0.06, -0.12 and -0.19, respectively). Oil content was significantly negatively correlated with protein content (-0.47*) in 2009, while in 2008 and 2010 this correlation was insignificant (-0.25, -0.11). This research is a basis for further breeding of soybeans with improved grain yield and content of protein and oil. Source

From 2008 to 2013 the phenology, early tree growth, precocity, yield, fruit quality attributes and leaf nutrient status of four sweet cherry cultivars (May Early, Germersdorfer, Sunburst and Celeste) were evaluated on Colt rootstock in the Cacak region (Serbia) with 1,250 trees/ha. The soil type was heavy and acidic. The results showed that cv. May Early blossomed and ripened earlier than the other cultivars, and had the highest tree vigour, better yield performance and the poorest fruit physico-chemical attributes. The best fruit quality was found in cv. Sunburst which is categorized as a low precocious cultivar with small yield capacity. Lower tree vigour, good productivity and fruit quality were shown by cv. Celeste. In general, leaf analysis indicated that all cultivars had excessive levels of N and Cu, and in some cases P, whereas K, Ca, Mg, Fe, Mn, Zn and B were deficient in all cultivars. The best balanced nutritional values (∑DOP) were observed in cv. Sunburst, whereas wider imbalance was observed in cv. Celeste for macronutrients. In contrast, the ∑DOP for micronutrients indicated that cv. Celeste had the best balanced nutritional values, whereas cv. Sunburst had the worst. Source

Molecular diversity of 145 barley (Hordeum vulgare subsp. vulgare L.) accessions from the Serbian GenBank was assessed by single sequence repeats (SSR) markers. A set of 15 SSRs, covering all chromosomes of the diploid barley genome with 2-3 SSR markers per chromosome, with a range of 4-18 alleles per locus were used. In total, 15 loci and 119 alleles were detected, with an average of 7.93 alleles per locus. The Polymorphic information content value ranged from 0.220 to 0.782 with a mean value of 0.534. Regarding the growth habit and row type groups, gene diversity was comparatively higher for the spring (0.616) and six-rowed accessions (0.616) than for the winter and tworowed accessions (0.322 and 0.478, respectively). Analysis of molecular variance showed that all sources of variation were significant (P < 0.01), but the between- group component was predominant (76.85%) for growth habit and 89.45% for row type. Unweighted Pair Group Method with Arithmetic Mean (UPGMA) cluster analysis based on the shared allele distance (DSA) matrix estimated on the SSR data assigned the genotypes into two clusters - the first smaller consisting of the six 6-rowed spring cultivars and the second comprising six subclusters. Genotype MBR1012 was separated from all other genotypes that constitute UPGMA tree. The associations of genotypes belonging to different growth habit and row type groups were assessed using Principal Coordinate Analysis revealing separation of winter growth habit group from facultative one. The use of the STRUCTURE clustering algorithm allowed the identification of 2 subpopulations of genotypes. Source
