The varietal screening studies of ten maize genotypes were carried out under field conditions with artificial infestation of Sesamia inferens and the classification of the maize genotypes was done based on the dead hearts and leaf injury rating. Among the ten maize genotypes, Madhuri (5.03) was classified as highly resistant genotype, while BML 7 (5.33) was placed under resistant category. The genotype, HKI 163 (5.87) was classified as moderately resistant genotype. The remaining five genotypes viz., HQPM 1 (6.50), MP 717 (6.93), BML 6 (7.03), BH 40625 and BH 1576 (7.90) were grouped as highly susceptible.

Abstract


The varietal screening studies of ten maize genotypes were carried out under field conditions with artificial infestation of Sesamia inferens and the classification of the maize genotypes was done based on the dead hearts and leaf injury rating. Among the ten maize genotypes, Madhuri (5.03) was classified as highly resistant genotype, while BML 7 (5.33) was placed under resistant category. The genotype, HKI 163 (5.87) was classified as moderately resistant genotype. The remaining five genotypes viz., HQPM 1 (6.50), MP 717 (6.93), BML 6 (7.03), BH 40625 and BH 1576 (7.90) were grouped as highly susceptible.
