AB  - Detecting genes that influence biofortification traits in cereal grain could help increase the concentrations of bioavailable mineral elements in crops to solve the global mineral malnutrition problem. The aims of this study were to detect the quantitative trait loci (QTLs) for phosphorus (P), iron (Fe), zinc (Zn), and magnesium (Mg) concentrations in maize grain in a mapping population, as well as QTLs for bioavailable Fe, Zn, and Mg, by precalculating their respective ratios with P. Elemental analysis of grain samples was done by coupled plasma-optical emission spectrometry in 294 F(4) lines of a biparental population taken from field trials of over 3 years. The population was mapped using sets of 121 polymorphic markers. QTL analysis revealed 32 significant QTLs detected for 7 traits, of which some were colocalized. The Additive-dominant model revealed highly significant additive effects, suggesting that biofortification traits in maize are generally controlled by numerous small-effect QTLs. Three QTLs for Fe/P, Zn/P, and Mg/P were colocalized on chromosome 3, coinciding with simple sequence repeats marker bnlg1456, which resides in close proximity to previously identified phytase genes (ZM phys1 and phys2). Thus, we recommend the ratios as bioavailability traits in biofortification research.

AB  - Although highly polymorphic SSRs are currently the marker of choice worldwide in maize breeding, single nucleotide polymorphisms (SNPs) as a newer marker system are recently used more extensively. The objective of this study was investigate the utility of SSR and SNP markers for mapping of a maize population adapted to conditions of Southeast Europe. Total of 294 F2:3 lines derived from a biparental mapping population were genotyped using 121 polymorphic SNP and SSR markers. The SNP markers were analyzed using the SNPlex technology. 56 of the 142 tested SNPs (39%) were polymorphic between the parents of the mapping population and were successfully mapped. The remaining markers were either not functional (5 = 3.5%) or not polymorphic (81 = 57%). No mapped SNP marker showed more than 10% missing data. On average, the level of missing data for SNPs (1.5%) was considerably lower than that for SSRs (3.4%). For the mapping procedure, the SNP data were combined SSR data. A comparison of the mapping data with the publicly available mapping data on SSR markers and the proprietary mapping data indicates that the map is of good quality and that the map position of almost all markers agrees with their published map position. Thus, information obtained from both marker systems is utilizable for further QTL analysis.
AB  - Iako su trenutno visoko polimorfni SSR markeri izbora, novi markeri SNP se od nedavno koriste veoma intenzivno u programima oplemenjivanja kukuruza u svetu. Cilj ovog istraživanja je ispitivanje primene SSR i SNP markera za mapiranje populacije kukuruza koje su prilagođene uslovima Jugoistočne Evrope. Ukupno 294 F2:3 linija dobijeno iz biparentalne mapirajuće populacije je analizirano sa 121 polimorfnim SNP i SSR markerom. SNP markeri su analizirani primenom SNPlex tehnologije. Pedeset šest od 142 ispitanih SNP markera (39%) je bilo polimorfno između roditelja mapirajuće populacije i uspešno je mapirano. Preostali markeri su bili ili nefunkcionalni (5=3,5%) ili nisu bili polimorfni (81=57%). Nemapirani SNP markeri su imali više od 10% podataka koji su nedostajali. U proseku, nivo podataka koji su nedostajali za SNP (1,5%) je bio značajno niži nego za SSR (3,4%). Za mapiranje kombinovani su SNP i SSR podaci. Poređenje mapirajućih podataka sa javno dostupnim mapirajućim podacima za SSR i zaštićenim mapirajućim podacima ukazuje da je mapa dobrog kvaliteta i da se pozicije na mapi skoro svih markera slažu sa njihovim prethodno objavljenim pozicijama. Otuda, informacije dobijene primenom oba marker sistema se mogu koristiti za buduće QTL analize.
