Occurrence and molecular characterization of Meloidogyne graminicola on rice in Central Punjab, Pakistan.

ABSTRACT: Meloidogyne graminicola threatens global rice production, yet is understudied for many areas where it is cultivated. To better understand the prevalence and incidence of M. graminicola in central Punjab, Pakistan, we carried out field surveys of rice fields in the districts of Faisalabad and Chiniot. M. graminicola isolates were recovered from soil and root samples and identified on the basis of perineal patterns and rDNA ITS-based sequencing. The severity of nematode attack on rice roots and infested fields at various locations was based on galling index, root-knot nematode juveniles per root system, juveniles per 100 ml of soil, and prevalence of stylet-bearing nematodes and non-stylet-bearing nematodes. Maximum prevalence (22.5 and 27.5%) and minimum prevalence (17.5 and 20%) of M. gram
