Abstract

Studies on potato cyst nematode, Globodera rostochiensis were conducted at two locations to ascertain, (i) the chances of its establishment post introduction at relatively lower altitudes (lower than 2000 m AMSL) and (ii) number of generations under north Indian conditions. The first experiment involved pot culture studies using artificially inoculated/naturally infested soil. The nematode did not develop on potato cv. Kufri Jyoti at lower altitude (1290 m AMSL) location of Palampur, Himachal Pradesh. The second experiment was conducted in naturally-infested field site at Nathatop, Jammu & Kashmir (2558 m AMSL). The nematode development was traced in situ through periodic observations on its life cycle stages. G. rostochiensis completed one generation (juvenile penetration to cyst containing eggs) in 40 days on potato cv. Kufri Girdhari (mean air temperature 11.88-14.7°C). The study signifies that nematode dissemination through seed material at locations below 2000 m AMSL may not be c
