Abstract

Hippeastrum/amaryllis (Hippeastrum hybridum Hort.) belongs to Amaryllidaceae. Plants of the hippeastrum 
exhibiting virus-like symptoms of chlorotic ring spots and concentric oval patterns were found in the collection 
of ornamental geophytes of the Ornamental Plants Research Center, Mahallat, Iran. Amplification of the 
genome using general primers of the Orthotospovirus genus, and specific primers of capsicum chlorosis virus 
(CaCV) led to the amplification of the expected fragments in some of the collected samples. Sequencing of 
amplified fragments proved the infection of some of the samples with CaCV and iris yellow spot virus (IYSV).
No simultaneous infection with these two viruses was observed in any of the samples. This is the first report 
of the occurrence of members of the genus Orthotospovirus on the hippeastrum plant from Iran.
