Evaluation of chickpea genotypes for resistance to legume pod borer (Helicoverpa armigera) and root-knot nematode (Meloidogyne javanica)
Twenty-one chickpea genotypes were screened for resistance to identify genotypes with multiple resistance in glasshouse and field. Genotypes, ICC 506, ICCV 10, ICCL 86102, and ICCV 95992 had a low pod damage rating of 3 (on a 1 = less susceptible to 9 = highly susceptible scale) to H. armigera. All the 21 genotypes were susceptible to nematode-caused root damage (galls on root) and nematode reproduction (egg sac production). ICCL 86102 showed tolerance to nematode damage and produced flowers and pods despite severe nematode infection. ICCL 86102, a short duration genotype, and ICCL 86106, a medium duration genotype were identified as promising sources with resistance to H. armigera and tolerance to M.javanica.
