Description Interaction of Meloidogyne javanica and Fusarium oxysporum f. sp. cice~q was studied on Fusarium
wilt-susceptible (JG 62 and K 850) and resistant (JG 74 and Avrodhi) chickpea cultivars. In
greenhouse experiments, inoculation of M. javanicajuveniles prior to F. oxysporum f. sp. ciceri caused
greater wilt incidence in susceptible culfivars and induced vascular discoloration in roots of resistant
cultivars. Nematode reproduction was greatest (P = 0.05) at 25 °C. Number of galls and percentage of
root area galled increased when the temperature was increased from 15 °C to 25 °C. Wilt incidence was
greater at 20 °C than at 25 °C. Chlorosis of leaves and vascular discoloration of plants did not occur at
15 °C. The nematode enhanced the wilt incidence in wilt-susceptible cultivars only at 25 °C. Interaction
between the two pathogens on shoot and root weights was significant only at 20 °C, and F. o. ciceri
suppressed the nematode density at this temperature. Wilt incidence was greater in clayey (48% clay)
than in loamy sand (85% sand) soils. The nematode caused greater plant damage on loamy sand than
on clayey soil. Fusarium wilt resistance in Avrodhi and JG 74 was stable in the presence of M. javanica
across temperatures and soil types.
