AB  - Interest in wheat breeding for low phytic acid content arised from its roll as antinutrient factor which chelates mineral elements (Ca, Zn, Fe, Mn, Cu and P), leading to their inadequate use. Excretion of unused P in phytic acid complex through non-ruminant animals such as poultry, swine and fish causes water eutrophication. Numerous indirect methods (e.g. spectrophotometric) and direct methods (HPLC - High Performance Liquid Chromatography) were developed for fast and accurate phytic acid determination in wheat. It typically represents 50-85% of seed total phosphorus and one to several percents of dry seed weight. Phytic acid content and phytate phosphorus genetic variability have been determined for wheat cultivars and lines under different environmental conditions. Wheat mutant (Triticum aestivum L) for low phytic acid content Js-12-LPA was created through breeding efforts.
AB  - Potreba za oplemenjivanjem pšenice na nizak sadržaj fitinske kiseline proistekla je iz njene uloge antinutritivnog faktora koji vezujući mineralne elemente (Ca, Zn, Fe, Mn, Cu, kao i P) dovodi do njihovog nedovoljnog iskorišćavanja. Neiskorišćeni fosfor u kompleksu sa fitinskom kiselinom se preko lanca ishrane nepreživara (živina, svinje, ribe) izlučuje u spoljašnju sredinu i uzrokuje zagađivanje vodenih ekosistema. Razvijene su brojne indirektne (spektrofotometrijske) i direktne (HPLC - High Performance Liquid Chromatography) metode za brzo i pouzdano utvrđivanje sadržaja fitinske kiseline u zrnu pšenice. Brojna istraživanja u svetu su pokazala da se sadržaj fitinske kiseline kreće od jedan do nekoliko procenata suve mase semena i 50% do 85% ukupnog fosfora u semenu. Utvrđena je značajna genetička varijabilnost sadržaja fitinske kiseline i fitatnog fosfora u zrnu sorata i linija pšenice u različitim uslovima spoljašnje sredine. Oplemenjivanjem je dobijen i mutant pšenice (Triticum aestivum L) Js-12-LPA, za osobinu niskog sadržaja fitinske kiseline (Low phytic acid).

AB  - This study was conducted to assess drought tolerance and regional-based patterns of diversity of bread wheat accessions and to identify new sources of diversity that could accelerate the development of improved wheat varieties better suited to meeting the challenges posed by changing climate in Southern and Eastern Europe. For this, genetic diversity assessed by simple sequence repeats (SSR) markers was compared with diversity evaluated using 19 phenotypic traits averaged over irrigated and drought-stress field conditions. Thirty-six SSR were used to profile 96 wheat genotypes from the collection of genetic resources at the Institute of Field and Vegetable Crops, Novi Sad, Serbia. A total of 46 loci and 366 alleles were detected, with a range of 3-21 alleles per locus. The polymorphic information content was estimated to be 0.61. The genetic distance for all possible 4560 pairs of genotypes ranged from 0.06 to 0.91 with an average of 0.65. Genotypes were grouped according to their drought tolerance (high, medium, low) and region of origin. Analysis of molecular variance showed that over 96% of the total variation could be explained by the variance within the drought tolerance and geographical groups. As a whole, genetic diversity among the high drought tolerance genotypes was considerably higher than that among low drought tolerance genotypes. Comparative analysis of SSR diversity among six regional groups revealed that the genotypes from North America exhibited more genetic diversity than those from other regions. Two dendrograms were constructed based on phenotypic and molecular analyses using the Unweighted Pair Group Method with Arithmetic Mean method and were found to be topologically different. Genotypes characterised as highly drought tolerant were distributed among all SSR-based cluster groups. This implied that the genetic basis of drought tolerance in these genotypes was different, thereby enabling wheat breeders to combine these diverse sources of genetic variability to improve drought tolerance in their breeding programs.
