Abstract

A survey was carried out in Paraguay to investigate the prevalence and distribution of sweet potato virus diseases. Two DNA viruses, Sweet potato pakakuy virus (SPPV) and Sweet potato symptomless virus (SPSMV), and three RNA viruses, Sweet potato feathery mottle virus (SPFMV), Sweet potato virus G (SPVG), and Sweet potato virus C (SPVC), were detected. They were cloned and sequenced. Sequences were deposited in GenBank of the National Center for Biotechnology Information. Of 53 samples from which viruses were detected, SPVG was detected in 29, representing 57.6% of virus-detected samples. The second most common virus was SPFMV. It was detected in 23 samples. This is the first report of a sweet potato virus disease outbreak in Paraguay confirmed through viral sequence analysis.
