TOMATO (LYCOPERSICON ESCULENTUM) VARIETIES FOR SUSCEPTIBILITY/RESISTANCE TO ROOT - KNOT NEMATODE (MELOIDOGYNE SPP) DISEASE IN ABAKALIKI AGRO-ECOLOGY



ABSTRACT
Three (3) tomato varieties: UTC Jos, Abakaliki Local and Tiv Local were evaluated for susceptibility/resistance against root-knot nematode disease in Abakaliki sandy clay loam soil. The study was carried out in randomized complete block design (RCBA) with four (4) replications. Results showed that UTC Jos was most susceptible to the disease as highest number of galls was recorded on it. Next in susceptibility to the disease was Tiv Local. The tomato variety Abakaliki Local was least affected by the nematode. Reduction in tomato fruit yield was highest on UTC Jos which was most affected by the nematode. The same was true for chlorotic and wilting symptoms associated with the disease.
