Exserohilum turcicum (Pass.) Leonard and Suggs is one of
the most important foliar diseases of Maize. Host-plant
resistance provides sustainable disease management option.
With an objective to identify new source of resistance to
TLB, 237 newly developed maize inbred lines were evaluated
for two consecutive years at four location in India
(Dharwad, Mandya, Almora and Bajaura) under artificially
created disease epiphytotics. The disease reaction of
individual genotype was rated on 1-9 scale. On the basis
of pooled mean over locations, 41 inbred lines were found
resistant (disease incidence <3.0), 181 inbred lines were
moderately resistant (disease incidence 3.1-5.0) and 15
inbred lines were moderately susceptible (disease incidence
5.1-7.0). Out of 41 inbred lines, 33 lines viz. IMLSB-57-2,
IMLSB-119-1, IMLSB-143-1, IMLSB-205-1, IMLSB-244-
1, IMLSB-246-2, IMLSB-266-2, IMLSB-306-1, IMLSB-
317-1, IMLSB-334B-1, IMLSB-343-1, IMLSB-343-2,
IMLSB-380-1, IMLSB-428-2, IMLSB-446-2, IMLSB-475-
2, IMLSB-568-2, IMLSB-748-1, IMLSB-801-2, IMLSB-
807-1, IMLSB-825-2, IMLSB-955-1, IMLSB-956-2,
IMLSB-975-2, IMLSB-976-2, IMLSB-1018-1, IMLSB-
1041-4-1, IMLSB-1043-1-1, IMLSB-1299-1, IMLSB-
1299-7, IMLSB-1381, IMLSB-2034, IMLSB-2136 were
resistant at three locations and across location (mean basis),
whereas 8 inbred lines IMLSB-282-2, IMLSB-310-2,
IMLSB-1046-3-1, IMLSB-1047-1-1, IMLSB-1376,
IMLSB-2051, IMLSB-2119, IMLSB-2166 were resistant
at two locations and across mean basis. These 41 maize
inbred lines, possessing resistance to turcicum leaf blight
can be used successfully in developing promising hybrids.Not Availabl
