Abstract

First report of potato cyst nematode (Globodera rostochiensis) infecting potato (Solanum tuberosum) in Rwanda.

Abstract

In August 2017, a survey was conducted to characterize the plant parasitic nematodes associated with potato (Solanum tuberosum) in Rwanda. Rounded cysts were found in 4 of the 10 samples collected. The highest density of cysts (89 cysts/100 cm3 of soil) was found in Rubavu, and lower densities of 17, 8, and 7 cysts/100 cm3 of soil were recorded in Musanze, Rubavu, and Burera districts, respectively. Based on morphological characteristics and molecular data (ITS rDNA sequence), the nematode was identified as Globodera rostochiensis. This is thought to be the first report of G. rostochiensis infecting potato in Rwanda.
