ABSTRACT:

Life cycle of Meloidogyne graminicola was studies on wheat at two sowing times under green house conditions at Hisar in India. In October-sown plants, second stage juveniles (J2) readily penetrated roots, developed to adult females in 24 days and started laying eggs in 38 days. However, majority of eggs hatched only in the month of February. Comparatively fewer J2 penetrated in November-sown plants and developed slowly to adulthood in 100 days. Eggs and J2 of next generation were recorded 110 days after inoculation. Wheat crop grown in heavily M. graminicola-infested fields after rice though showed a little root infection but no above-ground symptoms. These studies indicated that M. graminicola is not likely to become a pest on November-sown wheat in rice-wheat cropping system.
