K. Petrzik et P. Svoboda, SCREENING OF APPLE MOSAIC-VIRUS IN HOP CULTIVARS IN THE CZECH-REPUBLIC BY REVERSE TRANSCRIPTION-POLYMERASE CHAIN-REACTION, Acta virologica, 41(2), 1997, pp. 101-103
Thirteen cultivars of hop (Humulus lupulus L.) were tested by reverse
transcription-polymerase chain reaction (RT-PCR) for the presence of a
pple mosaic virus (ApMV). The virus was detected in various amounts in
all tested cultivars. Control hop clones derived from tissue cultures
, treated by thermotherapy and maintained in greenhouse were virus-fre
e. The procedure for sample preparation and RT-PCR of ApMV is describe
d in detail.
