Abstract
The aim of this study was to determine the effect presence populations of yellow potato cyst nematode Globodera rostochiensis (Wollen, 1923; Behrens, 1975) on the yield 15 different varieties of potatoes, during 2008. Investigations were carried out in the locality Planina mountain Jagodnja, near Krupanj, West Serbia. The susceptible potato varieties on y-PCN pathotype Ro1: Desiree, Cleopatra, Riviera, Romano and Virgo, which was exhibited a high degree sensitivity to y-PCN pathotype Ro1 in the locality Planina. Potato cultivars: Agria, Arnova, Kuroda, Rocco, Amorosa, Sante, Tomensa, Jelly, Navigation and Eldena, which are declared as resistant on Ro 1 y-PCN, has been resistant-on root system we not found female and cysts of y-PCN, and in soil male of y-PCN. The lowest yield was observed for suscep­tible varieties Romano (15.2 t ha-1) and Cleopatra (16.7 t ha-1), and the highest yield for resistant varieties Naviga (44.8 t ha-1) and Eldena (33.3 t ha-1). Obtained results indicate the p...ractical importance of growing resistant varieties in the infected areas of Mačva District in order to achieve higher yields of potatoes and eradicate the quarantine nematode G. rostochiensis.

Tokom 2008. godine ispitivan je uticaj prisustva populacije žute krompirove cistolike nematode Globodera rostochiensis (ž-KCN) patotip Ro1 na prinos 15 različitih sorti krompira. Istraživanja su izvedena na lokalitetu Planina na Jagodnji kod Krupnja u zapadnoj Srbiji. U istraživanjima korišćene su sledeće osetljive sorte krompira prema ž-KCN Ro1: Desiree, Cleopatra, Riviera, Romano i Virgo, koje su ispoljile visok stepen neotpornosti (osetljivosti) prema Ro1 ž-KCN u ispitivanom likalitetu. Sorte deklarisane kao otporne prema Ro1 ž-KCN ispoljile su visok stepen otpornosti prema ovom patotipu ž-KCN u lokalitetu Planina (Agria, Arnova, Kuroda, Roko, Amorosa, Sante, Tomensa, Jelly, Naviga i Eldena). Najmanji prinos utvrđen je kod osetljivih sorti Romano (15,2 t ha-¹) i kod sorte Cleopatra 16,7 t ha-¹, dok je najveći prinos krtola krompira ustanovljen kod otpornih sorti Naviga 44,8 t ha-¹ i Eldena 33,3 t ha-¹. Dobijeni rezultati ukazuju na praktični značaj gajenja otpornih sorti na zaraženo...m području u Mačvanskom okrugu u cilju postizanja većih prinosa krompira i iskorenjavanja karantinske nematode G. rostochiensis.
