Abstract:
The field experiment was conducted at Main Maize Research Station, Anand Agricultural University, Godhra during kharif 2019 & 2020 and Entomology farm, Department of Entomology, BACA, AAU, Anand during kharif 2020 to screen the maize hybrids, inbred lines, composite varieties, sweet corn and pop corn hybrids for resistance against fall armyworm, Spodoptera frugiperda (J. E. Smith). During the period of investigation, 09 hybrid maize cultivars (GAYMH 1, GAYMH 3, GYH 1603, GYH 1703, GWH 1257, GWH 1005, GWH 1604, GWH 1704 and GAWMH 2), 09 inbred lines (yellow maize-HO7R-4-3, LM-13-2, I-07-63-18-5, I-07-63-36-2 and white maize-CML 176, IL-15-52, 40527, CML 260, IL-15-50), 02 composite varieties (white maize- GM 6, NARMADA MOTI), 03 sweet corn hybrids (yellow maize- GSCH 0918, GSCH 1601, GSCH 0915) and 01 pop corn hybrid (yellow maize- IGPHC 1603) were evaluated based on the leaf damage rating scale (1-9). Among all the maize cultivars evaluated, significantly the lowest leaf damage rating scale was observed in hybrid maize cultivars viz., GAYMH 3, GAYMH 1 and GAWMH 2 as well as composite varieties viz., NARMADA MOTI and GM 6 and proved as resistant cultivars, whereas the highest leaf damage rating scale was observed in sweet corn hybrid GSCH 0918 and found susceptible under natural condition.
