Forty seven chickpea accessions were evaluated for their reaction to Meloidogyne incognita in pot experiments. Three-week-old seedlings were inoculated with 1000 freshly hatched juveniles of M. incognita. Sixty days after inoculation the plants wereuprooted and examined for galls, number of eggs/egg mass, root/shoot lengths and weights, and final nematode population. Variety RSG 564 was the most susceptible, developing the highest number of galls, eggs/egg mass and final nematode population, and variety RSG 617 was the least susceptible showing the lowest number of galls, eggs/egg mass and final nematode population and the highest root/shoot lengths and weights. All the other varieties exhibited degrees of susceptibility between RSG 564 and RSG 617.
