Molecular markers are essential tool for determining the specific genetic makeup of an individual and are valuable approach for genetic improvement of farm animals. In cattle breeding their application is useful for improvement of breeding programs for desired traits, better productivity and high quality products. These markers provide more accurate genetic information and better knowledge of the animal genetic resources. In this review we attempt to make a brief summary on the application of one of more advanced DNA-based molecular markers in cattle breeding, namely short tandem repeat (STR, microsatellites). Molekularni markeri su suštinsko sredstvo za određivanje specifičnog genetičkog sastava pojedinca i predstavljaju dragoceni pristup genetičkom oplemenjivanju farmskih životinja. U stočarstvu njihova primena je korisna za poboljšanje programa odgajivanja za željene osobine, veću produktivnost i proizvode visokog kvaliteta. Ovi markeri pružaju preciznije genetske informacije i bolje poznavanje genetičkih resursa životinja. U ovom preglednom radu pokušavamo da napravimo kratak pregled o primeni jednog naprednijeg molekularnig markera zasnovanog na DNK u stočarstvu, a to su kratki tandemski ponovci (STR, mikrosateliti).

New designed cultivars Sila, Nova Dinka and Riesling Italian clone 13, were examined in the frame of investigation dedicated to the influence of more frequently used rootstocks, on new cultivars designed in Institute for fruitgrowing, viticulture and hoticulture, from Faculty of Agriculture in Novi Sad. Vineyard where investigations are performing was planted in 1992 and 1993, with Karlovački training system established. Investigated cultivars were grafted on the next rootstocks: kober 5BB as a standard, T5C, SO4 and 41B. At the all vinestocks vines have the same nutrient area (3,6 m2), and the same bud loading (7,2 buds/m2), and agro and phito technics was performed. According to standard methods data about potential and real fertility and quality of yeald were collected. The best results cultivars Sila and Nova Dinka showes grafted on SO4 rootstock, but they can be grafted and succesfuly trained on kober 5BB and T5C, while 41B rootstock is not appropriate for these cultivars. Cultivar Riesling Italian clone 13 showes best results grafted on SO4 rootstock. U okviru ogleda koji je postavljen da bi se utvrdio uticaj najčesće korišćenih loznih podloga na neke novostvorene sorte i Monove Instituta za voćarstvo i vinogradastvo, Poljoprivrednogfakulteta iz Novog Sada, ispituju se i novostvorene sorte sila, nova dinka i rizling italijanski klon 13. Vinograd u kome se obavljaju ispitivanja je posađen 1992. i 1993. godine, a zasnovan je karlovački uzgojni oblik čokota. Sorte sila, nova dinka i rizling italijanski kalemljene su na lozne podloge kober 5BB kao standard, T5C, SO4 i 4IB. Svim čokotima je data jednaka hranidbena površina (3,6 m2), primenjeno je isto opterećenje okcima (7,2 okca/m2) i agro i fito tehnika. Između velikog broja raznih podataka, standardnim metodama su prikupljani i oni o mogućoj i stvarnoj rodnosti, i kvalitetu roda. Ispitivane sorte su najbolje rezultate pokazala na podlozi S04. Sorte sila i nova dinka se sa velikim uspehom mogu gajiti na loznim podlogama kober 5BB i T5C, a rizling italijanski na podlozi 4IB, dok sili i novoj dinki ova podloga ne odgovara.
