A study on the host reactions of the five populations of Meloidogyne incognita collected from five widely separated regions of India revealed the presence of inter and intra population differences. Considering the reactions on differentials used by the International Meloidogyne Project, these populations are similar to race 1 and/or race 2 of M. incognita. Based on the reactions on cowpea var. 82-1B, Delhi and Udaipur populations form one group different from Jabalpur, Kanpur and Kerala populations.
