Resumen
Tamarillo is one of the fruit crops with the highest potential
for being intensively produced in the Colombian
Andes, because it has a great quantity of organoleptic
and nutritional characteristics interesting for
food industries and for the national and international
fresh fruit markets. These conditions, added to its
use as a substitute for illegal crops in Colombia, led
to the increase of the area planted with this product
in the 1990´s decade, reaching almost 7.500 hectares.
However, this situation recently had a dramatic
change due to phytosanitary problems, among which
anthracnose (Colletotrichum acutatum) and virosis
can be remarked. The latter, according to recent research
works, is caused by a complex conformed by,
at least, four main viruses (Potyvirus, PLRV, CMV
and ToMV) and others, apparently less influential
(AMV, ToRSV andf TSWV). Due to the great impact
this disease has had on the expansion plans of the
tamarillo cultivation in Colombia, this revision introduces
a detailed description of the main viral groups
associated to virosis, emphasizing the characteristics
of their genomes, which is the information base
to design tools to detect the viruses.
