With 5 figures and tables Abstract Landraces of wheat ( Triticum aestivum L.), collected from the Western Balkans, were considered as a potential genetic resource drought resistance for breeding. A group 20 landraces with 80 accessions worldwide origin tested in 4‐year field trials under two watering regimes: fully irrigated rain‐out plot shelter. Fourteen agronomic traits evaluated their responses to stress, four selection indices calculated: mean productivity (MP), stress tolerance (TOL),...

Genetic analyses and association mapping were performed on a winter wheat core collection of 96 accessions sampled from variety geographic origins. Twenty-four agronomic traits evaluated over 3 years under fully irrigated, rainfed drought treatments. Grain yield was the most sensitive trait to water deficit highly correlated with above-ground biomass per plant number kernels m2. The germplasm structured into four subpopulations. 46 SSR loci distributed throughout genome analyzed using...

Nitrogen fertilization have influence on protein, oil and trypsin inhibitor content of different soybean genotypes. Seed protein was increased over control by 60 kg ha-1 nitrogen while reduced all treatmens (30, 60,90 N ha-1) as compared to controls. Significant genetic variation in TI found both within the genotype class with Kunitz present well lacking this inhibitor. Genotypes containing (KTI) exhibit a higher than genotypes however, groups similary affected application. Oil following...

SUMMARY When water stress develops post-anthesis, wheat ( Triticum aestivum L.) plants have to rely increasingly on remobilization of previously stored assimilates maintain grain filling. In two-year field trials, we studied more than 20 agronomic and developmental traits in 61 genotypes (27 F4:5 families, 17 parents used for the crosses standards), comparing that were defoliated (DP) by cutting off all leaf blades 10 days after anthesis with intact control (CP). Estimated contributions stem...

Summary The aim of this study was to compare five bread and durum wheat genotypes for gliadins glutenins profiles, the concentration free sulphhydryl groups disulphide bonds, antioxidant capacity gluten proteins their bread‐making performance. On average, had significantly higher total sulphur‐rich (S‐rich) sulphur‐poor (S‐poor) subunits gliadins, as well low molecular weight ( LMW ) high HMW than wheat. However, S‐rich γ‐gliadins S‐poor D‐ ‐glutenins, but did not possess ω‐gliadins. bonds...

Barley (Hordeum vulgare L.) is often grown in sites with low rainfall and high temperature during grain filling. Because spike architecture one of basic footprints barley domestication, the importance spikes adaptation to different environments or abiotic stresses can be hypothesised. In order compare types terms kernel growth yield components, we tested 15 two-row 10 six-row winter genotypes eight where terminal drought was simulated by defoliation at 7 days after heading (7 DAH). Control...

The objective of this study was to determine phenolic compounds and the total antioxidant capacity in grain ten bread (T. aestivum L.) durum Desf.) wheat genotypes. Soluble free forms phenolics, flavonoids, PVPP (polyvinylpolypyrrolidone) bound proanthocyanidins acids were investigated. In addition, correlation coefficients between capacities concentration different soluble compounds, as well phenolics acids, flavonoids determined. Significant differences content aceton/water extractable...

SUMMARY Assimilated carbon during vegetative and early reproductive growth in wheat is temporarily stored stem internodes leaf sheaths (LSs), can later be remobilized transported to developing grain. The present study was undertaken determine the effect of several peduncle (the uppermost internode) morpho-anatomical biochemical traits on grain weight, assess contribution water-soluble carbohydrate (WSC) reserves shortly after anthesis its variation. In 2-year field trials, 61 genotypes were...

Twenty-five varieties of wheat were used in this study order to determine the effect amylose and amylopectin, as well dietary fibers on pasting properties baking functionality whole-grain flour. The results compared refined analyzed samples divided into six groups based content: (1) 11%–14%, (2) 15%–17%, (3) 18%–19%, (4) high (36.5% 41%), (5) waxy (0%), 6) flour (22%). Amylose influenced viscosity by large, however, variations can be attributed differences non-starch structural components....

PA showed the least variability (CV...

In Serbia, aspergillus ear rot caused by the disease pathogen Aspergillus parasiticus (A. parasiticus) was first detected in 2012 under both field and storage conditions. Global climate shifts, primarily warming, favour contamination of maize with aflatoxins temperate climates, including Serbia. A five-year study (2012–2016) comprising 46 A. strains isolated from kernels performed to observe morphological, molecular, pathogenic, toxigenic traits this pathogen. The HPLC method applied...

Molecular diversity of 145 barley (Hordeum vulgare subsp. L.) accessions from the Serbian GenBank was assessed by single sequence repeats (SSR) markers. A set 15 SSRs, covering all chromosomes diploid genome with 2-3 SSR markers per chromosome, a range 4-18 alleles locus were used. In total, loci and 119 detected, an average 7.93 locus.

The set up at two locations for growing seasons (2011, 2012) treatments. One treatment (D) simulated by the mechanical removal all leaf blades 7 d after heading each genotype, a (C) which plants were left intact. On...

Post-anthesis drought affects wheat production worldwide, primarily through the limitation of grain filling. The enhanced remobilization stem reserves induced by can provide considerable carbon sources for aim this study, which was part an ongoing wheat-breeding program targeting tolerance, to assess ability 20 contrasting common genotypes (2 cultivars, 8 F6:7 families (FAM), and 10 parent (PAR) used make families) remobilize dry matter under water-stressed conditions simulated via...

In recent years, countries in Southeast Europe are facing climate changes characterized by extreme hot weather, which contribute to the increased frequency of Aspergillus species. Because these changes, parasiticus was isolated, for first time, from maize grain Serbia (Nikolic et al, 2018). The presence black powdery mycelia on ears indicated occurrence species genus section Nigri, led need detailed identification fungi. Disease incidence ranged 10 and 15% August 2013. Maize with symptoms...

Water-soluble carbohydrates (WSC) accumulating in internodes of the wheat stem can be a consequential contributor to grain filling, especially under stress conditions.In this study WSC content and specific (WSCSC) per unit length were determined uppermost internode (peduncle) main at 10 days after anthesis across 44 genotypes two-year field trials.The defoliation was done by cutting off all leaf blades defoliated plants grown along with intact control plants.Among 16 morphological,...
