Leprosis, caused by citrus leprosis virus
(CiLV) and transmitted by the tenuipalpid mite
Brevipalpus phoenicis, is one of the most important
viruses of citrus in the Americas. Sweet oranges
(Citrus sinensis L. Osb.) are highly susceptible to
CiLV, while mandarins (C. reticulata Blanco) and
some of their hybrids have higher tolerance or resistance
to this disease. The mechanisms involved in the
resistance and its inheritance are still largely unknown.
To study the quantitative trait loci (QTL; quantitative
trait loci) associated with the resistance to CiLV,
progeny analyses were established with 143 hybrid
individuals of ?Pêra? sweet orange (C. sinensis L. Osb.)
and ?Murcott? tangor (C. reticulata Blanco 9
C. sinensis L. Osb.) from controlled crossings. Disease
assessment of the hybrid individuals was conducted by
infesting the plants with viruliferous mites in the field.
The experiment consisted of a randomized completely
block design with ten replicates. The evaluated phenotypic
traits were incidence and severity of the
disease on leaves and branches, for a period of 3 years.
The MapQTLTM v.4.0 software was used for the
identification and location of possible QTL associated
with resistance to CiLV on a genetic map obtained
from 260 AFLP and 5 RAPD markers. Only consistent
QTLs from different phenotypic traits and years of
evaluation, with the critical LOD scores to determine
the presence or absence of each QTL calculated
through the randompermutation test, were considered.
AQTL was observed and had a significant effect on the
phenotypic variation, ranging from 79.4 to 84%
depending on which trait (incidence or severity) was
assessed. This suggests that few genes are involved in
the genetic resistance of citrus to CiLV. MenosLeprosis, caused by citrus leprosis virus
