VARIATION IN LENTIL GERMPLASM FOR REACTION TO VIRUS INFECTION MUHAMMAD BASHIR, TARIQ AZEEM*, ASGHAR ALI AND MUHAMMAD IJAZ*
Abstract: This study was conducted to assess the variation among lentil germplasm
for their reaction to natural virus infection and to identify sources
of resistance against viruses infecting lentil. Based on field observations
and ELISA, a great variation was observed among lentil genotypes for
their reaction to natural virus infection. Lentil was infected by pea
seed-borne mosaic virus (PSbMV), cucumber mosaic virus (CMV), bean yellow
mosaic virus (BYMV), broad bean stain virus (BBSV) and faba bean necrotic
yellows virus (FBNYV). PSbMV was the most common virus with 64 % of
lentil genotypes infected followed by CMV (35%), BBSV (16%), BYMV (14%)
and FBNYV (10%).
Out of 108 lentil germplasm accessions/breeding lines tested, none of
the genotypes was found as highly resistant. However, thirty (64%) and
9 (35%) genotypes were found as resistant and moderately resistant respectively
to viral diseases infection. Out of 9 moderately resistant genotypes,
four were from Pakistan (99CL-002, 97CL-010, 93CL-005, 11222), four
from Syria (FLIP 66-542, FLIP 96-582, ILL-7517, ILL-7537) and one from
Canada (ILL- 8105). All other lines were susceptible to highly susceptible.
