Abstract
The origin and evolution of maize has been attracting attention of researchers of different profiles for decades. Although a few researchers in our country have explicitly been dealing with these issues, it is necessary to survey studies within this field. Not only because of educational reasons, but also because revealing secrets on the origin and evolution provides knowledge about maize genome, which can influence the improvement of current breeding of this very important crop. The enhancement of genetic variability of commercial material is another crucial challenge faced by maize breeders. Therefore, a segment of this study is a reminder indicating that collected and described landraces conserved in the genebank of the Maize Research Institute 'Zemun Polje' are germplasm valuable to breeding programmes intended for moderate climate. Some inbred lines (ZPPE25-10-1; NS796; R70Ž; NS568) developed in our scientific institutions using adapted landraces were of a great commercial importa...nce for maize breeding programmes. However, little has been done on the improvement of landraces. Consequently, it is our opinion that some breeding efforts should be aimed at this topic in order to provide further progress in the maize breeding improvement.

Poreklo i evolucija kukuruza već decenijama zaokupljaju pažnju istraživača različitih profila. Iako se kod nas malo istraživača eksplicitno bavilo ovom problematikom postoji potreba da se prate istraživanja iz ove oblasti, ne samo iz obrazovnih razloga, već i stoga što se razotkrivanjem tajni porekla i evolucije stiču saznanja o genomu kukuruza, što može unaprediti savremeno oplemenjivanje ove važne kulture. Povećanje genetičke varijabilnosti komercijalnog materijala još jedan je važan izazov pred oplemenjivačima kukuruza. Stoga, deo ovog rada je podsećanje da sakupljene i opisane lokalne populacije, koje sa nalaze u banci gena Instituta za kukuruz Zemun Polje, predstavljaju vrednu germplazmu za oplemenjivačke programe namenjene umerenom pojasu. Neke inbred linije (ZPPE25-10-1; NS796; R70Ž; NS568) selekcionisane u našim naučnim institutima korišćenjem adaptiranih lokalnih populacija, imale su veliki komercijalni značaj za oplemenjivačke programe kukuruza. Unapređenju lokalnih populacij...a do sada nije posvećeno dovoljno pažnje. Smatramo da bi deo oplemenjivačkih napora trebalo usmeriti u ovom pravcu kako bi se obezbedio dalji progres u unapređenju dobiti od selekcije.
