Abstract

A survey was conducted in September 2019 in Abuja, to assess the incidence and severity of rice virus disease
across 24 rice fields. The samples collected from the survey were used for molecular indexing. All data collected
were subjected to statistical analysis using SPSS version 17 and mean separation was done using Duncan
Multiple Range Test. Out of 360 leaf samples collected from the survey, Bwari Area Council had the highest
incidence (35.5%), while Abuja Municipal Area Council (AMAC) had the lowest (13.3%). Gwagwalada had the
highest severity (31.1%) and AMAC recorded the lowest (20%). After testing in the laboratory using Polymerase
Chain Reaction (PCR), the samples did not test positive to the virus. This study is the first research on RSNV in
the FCT, Abuja and further survey is recommended for the FCT and other parts of Nigeria.
