| Description |
Apple is the major commercial horticulture
crop in Himachal Pradesh and other hill states of Jammu &
Kashmir, Uttarakhand and some parts of Northeastern
states of India. In order to gather data on health status and
incidence of virus and virus-like pathogens in apple orchards,
survey was conducted in the month of June and
September, 2010 in Hatkoti, Rohru, Kuthara, Jubbal and
Khadapathar areas of major apple producing Shimla district
of Himachal Pradesh. A total of 250 samples were
collected and analyzed by DAS-ELISA, NASH and RTPCR.
NASH results indicated that a total of 117 samples
were infected with Apple chlorotic leaf spot virus (ACLSV),
Apple mosaic virus (ApMV), Apple stem grooving
virus (ASGV), Apple stem pitting virus (ASPV) and Apple
scar skin viroid (ASSVd). Results showed that ASSVd is
predominant in these areas with highest infection rate of
27.6% followed by ASPV (17.2%), ACLSV (16.8%),
ApMV (15.2%) and ASGV (12%). Mixed infection of
these viruses and viroid was frequently detected in apple
trees in Himachal Pradesh. The trees, which were positive
for viruses and viroids, showed a variety of fruit deformation
and rusting symptoms besides leaf deformation,
mosaic and chlorosis.
