Response of Photosynthetic pigments such as chlorophyll and carotenoid content of moderately resistant (ADT 41, ADT 45, TRY 1, TPS 3, Swarna and GEB 24) and susceptible rice varieties (Co 47, Pusa Basmathi, ASD 19, Co 43, Co 2, Co 19 including TN 1 as susceptible check) induced by the root knot nematode, Meloidogyne graminicola were analysed. Photosynthetic pigments in moderately resistant and susceptible varieties were recorded 45 days after nematode inoculation. The study revealed that in moderately resistant varieties, chlorophyll and carotenoid contents were found to increase after nematode infestation.
