The objective of this work was to evaluate the reaction of chickpea genotypes to the Embrapa Vegetables germplasm bank for resistance to Meloidogyne incognitarace 1 and M. enterolobii, aiming to identify sources of resistance to these root knot nematodes,and to verify haw this culture is affected byM. enterolobii. Six genotypes of chickpea were evaluated: 'Jamu-96', 'Flipoz-23C', 'Flip 03-34C', 'Flip06-155C', 'FIip03-109C' and the cultivar BRS Cícero. The experiment was conducted in a completely randomized design in a 7x2 factorial scheme (seven genotypes x two species of nematodes), with six replications. The two nematodes species were inoculated in the chickpea genotypes, and 104 days after inoculation were evaluated the egg mass index (IMO) and gall index (IG), number of eggs per gram of root (NOGR) and of the reproduction factor (FR). The data were submitted to individual and joint analysis of variance for the two species of nematodes and grouping of means of the treatments by Scott-Knott test. Was verified that for both species root-knot nematodes were not possible to identify resistant chickpea genotypes, but as field control is difficult, researches such as these to search for sources of resistance are important.
