Abstract:
The field experiment was conducted at Research-Cum-Instructional Farm at College of Agriculture, IGKV, Raipur (C.G) during kharif 2021 to screen out thirty-three maize genotypes against fall armyworm, Spodoptera frugiperda. Out of thirty-three maize genotypes, ADV-768 (2.72) genotype recorded with minimum leaf damage. However, SWEET GLORY (8.52) genotype was recorded with maximum leaf damage. Maximum kernel damage was noticed in HT-520015 (4.96), while minimum kernel damage was observed in genotype HT-520169 (1.41). Significant but negative correlation was observed between leaf damage and leaf length with ‘r’ value -0.947. Leaf width has negative impact (r = -0.968) on leaf damage. Leaf trichome density showed significant but negative impact (r = -0.992) on leaf damage. Whereas kernel damage showed significant but negative correlation with cob length (cm) (r = -0.925).
