Abstract
Description
Tobacco (Nicotiana tabacum L.) is an important in-
dustrial crop. Among the diseases causing losses in tobacco cul-
tivation, viral ones are of particular importance due to the very
low effectiveness of chemical protection allowing only for vec-
tor control. The greatest threat to tobacco cultivation in Poland
and in many countries of the world is posed by potato virus Y
(PVY), tomato spotted wilt virus (TSWV) and, in recent years,
the increasingly frequent tobacco mosaic virus (TMV). The ge-
netic resources studies carried out in the genus Nicotiana have
shown a wide variation in species resistance, assessed biologi-
cally, serologically and molecularly, depending on the virus used
and, in the case of PVY, also on the specific isolate. The results of
the assessment of resistance in Nicotiana accessions presented in
this paper, gathered from literature data as well as from our own
research, allow us to broaden and systematise our knowledge on
the sources of resistance to viral diseases. This is the only such an
extensive study in this field. It provides an excellent information
base for the appropriate selection of accessions for use in resist-
ance breeding.
