The fall armyworm (FAW), Spodoptera frugiperda, has a detrimental effect on the
sustainable production of maize, particularly in India's small- and marginal-scale farming systems. FAW
has indeed spread throughout India, and currently the primary means of control is pesticide spraying.
Given the harmful effects of insecticide spray on natural enemies as well as resurgence and resistance
problems, there is a need to develop an effective, eco-friendly, and feasible techniques. A screening
experiment was carried out during 2021–22 in an insect screening net house under artificial infestation at
Winter Nursery Centre, ICAR-Indian Institute of Maize Research, Rajendranagar, Hyderabad, to identify
resistant/tolerant maize genotypes to fall armyworm. Twenty-two maize genotypes were evaluated based
on the fall armyworm leaf damage score on a scale of 1 to 9, as specified by Davis and Williams (1992),
which was later modified by CIMMYT. The pooled mean data of leaf damage score (LDS) per plant varied
from 3.93 to 6.84 in CML 71 and CM 501, respectively, and differed significantly from each other. Among
the maize genotypes screened, CML 71, CML 67 and DMRE63 recorded significantly lower leaf damage
scores of 3.93, 4.00 and 4.17, to fall armyworm. The mean leaf damage score per plant of CML 71, CML
67, DMRE63, CML 561, AEBY-1, CML 335, CML 345, and CML 337 were 3.93, 4.00, 4.17, 4.36, 4.42, 4.57,
4.72, and 4.80, respectively and were categorized as moderately resistant genotypes. These genotypes can
be utilized in breeding programmes to develop fall armyworm-resistant/tolerant cultivars.
