Experiments were conducted to screen ten eggplant cultivars viz., Dilnasheen, VRIB-04, VRIB-01, VRIBH-03, Cluster king, Faisalabad-Long, PPR, Purple Queen, Nirrala and Bemissal against Meloidogyne incognita infection in the green house at 25 plus minus 4 degree C. At harvesting, roots of Nirrala contained significantly fewer galls (45) and egg-masses (51) compared to the other nine cultivars. Nine cultivars including Dilnasheen, Purple Queen, VRIB-01, Faisalabad Long, PPR, Bemissal, VRIBH-03, VRIB-04 and Cluster king had 5 root galling and egg-masses indices (from a scale of 0-5). Out of ten, five cultivars viz., VRIBH-03, VRIB-01, VRIB-04, Cluster king and Dilnasheen were subjected for the invasion and development of M. incognita. All the varieties showed variability in their response to M. incognita infestation. Maximum invasion and development of nematodes was recorded in Dilnasheen followed by VRIBH-03 and Cluster king. Minimum invasion and development was recorded in VRIB-04. Root weight had direct relationship with the number of developing M. incognita.
