Chickpea (Cicer arietinum) is one of the most important food legumes grown worldwide. Its cultivation in India is hampered considerably due to regular occurrence of root knot nematode and reported to reduce the chickpea yield by 9-40%. The present study was conducted to evaluate some chickpea germplasm for resistance against root knot nematode, Meloidogyne incognita.The experimental result revealed that none of the germplasm was found highly resistant against the root knot nematode, however 9 germplasm lines were recorded resistant having 1.1 to 2.0 root gall index.12 germplasms exhibited moderately resistant with root gall index 2.33 to 3.0, 7 were found susceptible showing root gall index between 3.1 to 4.0 and thirty-two lines were found to be highly susceptible having root gall index between 4.1 to 5.0. Susceptible cultivars developed heavier root systems because of root galling compared to resistant cultivars. Similarly, resistant plants have shown more growth in shoot attributes conforms that the growth of root length, shoot length, fresh shoot weight and dry shoot weight is negatively correlated to the root knot index (r =-0.688, -0.773, -0.658, -0.705 respectively) while fresh root weight and dry root weight, were positively correlated with root knot index (r = 0.716, 0.296 respectively).
