摘要

Surveys, virus detection, and genetic characterization of viruses, piper yellow mottle virus (PYMoV) and cucumber mosaic virus (CMV) were conducted to update the status of stunt disease in black pepper in Indonesia. Disease intensity and PYMoV frequency in the Natar and Petaling varieties in Bangka and Lampung were relatively high, reaching 100%. In contrast, disease intensity in the Ciinten variety, in two plantations in Sukabumi was low, at 23 and 15%, respectively. CMV infection was detected in Sukabumi and Bangka at frequencies below 50%, and it consistently occurred as a double infection with PYMoV. Isolates of PYMoV showed considerable genetic diversity, forming four clusters, i.e. three clusters related to Indonesian isolates and one cluster related to isolates from China and India. CMV isolates showed closed genetic relationships with Indonesian isolates from banana and cat’s whiskers, indicating an expansion of CMV host range. This study is the first report of stunt disease occurrence in the Ciinten variety in Sukabumi.
