Abstract
The aim of this study was to determine the impact of the origin of planting material and size of seed tubers, on the productive properties of most commonly grown potato cultivars Cleopatra, Jaerla, Desiree and Kennebec in Western Serbia (Macva). Potato seed-producing crop, from which the planting material came from, was grown during 2007 at two sites with different altitude: a plain region 72 m a.s.l. and a mountainous region 1100 m a.s.l. Evaluating the presence of the two most widespread potato virus (PYV) and (PLRV in our conditions was performed by ELISA test. The investigation was carried out by planting the following mass of planted material: 50 ± 5g, 70 ± 5g, 90 ± 5g and 110 ± 5g in 2008 year. Planted tubers originating from 72 m a.s.l. produced a total yield of 29.10 t ha1- .The difference was higher than the variant with planted tubers originating from 1100 m a.s.l. by 1.30 t ha1- (4.50 %). The highest total yield of 30.80 t ha1- was achieved by planting the largest mass (110 ...g) and the lowest 25.50 t ha1- by planting the smallest mass (50 g) of the tuber.

Cilj rada je bio da se utvrdi uticaj porekla sadnog materijala i veličine semenske krtole na produktivne osobine četiri najčešće gajene sorte krompira Cleopatra, Jaerla, Desiree i Kennebec u uslovima Zapadne Srbije (Mačve). Proizvodnja sadnog materijala krompira izvedena je 2007. godine u dva lokaliteta različite nadmorske visine (nv): ravničarskom 72 m i planinskom regionu 1100 m (nv). Ocena prisustva dva i najraširenija virusa krompira u našim uslovima (PYV) i (PLRV) izvršeno je ELISA testom. Istraživanja su izvedena sadnjom semenskih krtola prosečne mase 50 ± 5g, 70 ± 5g, 90 ± 5g i 110 ± 5g tokom 2008. godine. Sađenjem krtola poreklom sa 72 m nv. u proseku ostvaren je ukupan prinos od 29,10 t ha1-. Razlika je veća od varijanti gde su sađene krtole poreklom sa 1100 m nv. za 1,30 t ha1-, ili za 4,50 %. Najveći ukupan prinos krtola od 30,80 t ha1- dobijen je sadnjom najkrupnije frakcije prosečne mase 110 g, a najmanji 25,50 t ha 1- sadnjom najsitnije frakcije prosečne mase 50 g.
