Twenty-five accessions of Cicer bijugum, C. chorassanicum, C. cuneatum, C, judaicum, C, pinnatifidum, and C. reticulatum, 173 chickpea advanced breeding lines and five cultivars were evaluated for resistance to Meloidogyne jauanica in a greenhouse. Resistance evaluation was on a 1-9 damage index (l=highly resistant; 9=highly susceptible) based on gall number, gall size, and galled area of root. Numbers of egg sacs were also counted. None of the tested lines was free of nematode damage. Damage indices of Cicer spp. ranged between 5.2 and 8.8. ICCW 47, an accession of C. cuneatum was less susceptible than other accessions. Variation in gall size was greater than that for gall number and galled area. Most of the tested lines showed symptoms of stress in terms of premature drying of leaves, chlorosis, and stunting of plants. Plant growth of two breeding lines (ICCV 90043 and 90243) and a cultivar (ICCC 42) was not affected by nematode parasitism, foliage of these genotypes remaining dark green and without premature leaf drop.
