Abstract:
At the N. M. College of Agriculture, Navsari Agricultural University, Navsari, Gujarat, during the summer of 2022, an investigation on the screening of eight different maize genotypes (GYH-1803, GYH-2009, GYH-1603, GYH-0952, GYH-1915, GYH-1801, GYH-1701, and GYH-1509) against fall armyworm was conducted. Three replications and a randomized block design were used to set up the experiment. The crop was planted with a 60 x 20 cm spacing. Based on leaf damage the maize genotypes, GYH-1509 and GYH-1701 were found moderately resistant however based on cob damage GYH-1801 genotype was found moderately resistant against fall armyworm. The ascending order of different maize genotypes was GYH-0952 > GYH-1603 = GYH-2009 = GYH-1701 > GYH-1915 = GYH-1509 = GYH-1803 > GYH-1801 as far as larval population on vegetative parts whereas, GYH-1509 > GYH-1803 = GYH-2009 = GYH-1603 = GYH-1915 > GYH-0952 = GYH-1801 = GYH-1701 on larval population in cob. In relation to susceptibility based on leaf damage, the descending order of genotype was GYH-1603 > GYH-1803 > GYH-2009 =GYH-0952 > GYH-1915 > GYH-1801 > GYH-1701 > GYH-1509 whereas based on damage in cob it was GYH-1803 = GYH-2009 > GYH-0952 > GYH-1603 = GYH-1915 > GYH-1701 = GYH-1509 > GYH-1801.
