AB  - In order to broaden the genetic base of maize (Zea mays L.) germplasm, it is necessary to integrate exotic materials into adapted breeding materials. The aim of the study was to compare antioxidative systems of two adapted maize inbred lines (A and B) with exotic germplasm, Drought Tolerant Population (DTP), and their backcrosses with DTP (A1, A2 and B1, B2). The content of low-molecular weight antioxidants, proline and phenolics, as well as antioxidant capacity, detected as free radical scavenging activities against DPPH radical, were measured in maize seeds. Proline content in both, embryo and endosperm was higher in backcrosses than in inbred lines and DTP, and increased in embryo by getting higher percentage of exotic germplasm. Contrary, phenolic content and DPPH radical scavenging activity of seeds, which were higher in adapted inbred lines than in DTP, were slightly decreased in their backcrosses with DTP.
AB  - U cilju proširenja genetičke osnove germplazme kukuruza (Zea mays L.), neophodna je inkorporacija egzotičnog u lokalni adaptirani selekcioni materijal. U radu su upoređeni antioksidativni sistemi dve lokalne inbred linije (A i B) sa antioksidativnim sistemima egzotične germplazme (DTP) i povratnih ukrštanja tih inbred linija i DTP-a (A1, A2, B1 i B2). U semenu kukuruza meren je sadržaj antioksidanata male molekulske težine, prolina i ukupnih fenola, kao i antioksidativni kapacitet, izražen preko sposobnosti hvatanja slobodnih DPPH radikala. Rezultati su pokazali porast nivoa prolina, kako u klici, tako i u endospermu, kod A1, A2, B1 i B2 genotipova, u odnosu na čiste inbred linije i DTP. Takođe, nivo prolina se povećavao sa povećanjem udela egzotične germplazme. Nasuprot tome, kod čistih inbred linija je bio veći nivo ukupnih fenola i stepen hvatanja slobodnih DPPH radikala nego kod DTP-a, i sa tendencijom neznatnog smanjenja kod A1, A2, B1 i B2 genotipova.
