Abstract

Stem borer (Sesamia calamistis) infestation remains a significant challenge in sorghum (Sorghum Bicolor (L.) Moench) cultivation, leading to substantial yield losses in Nigeria. This study is aimed at investigating the interrelationship between agronomic and resistant traits of stem borer (Sesamia calamistis), and its influence on selection. The study was carried out at the research field of Plant Breeding Unit, Department of Agriculture Biotechnology, National Biotechnology Research and Development Agency. Forty (40) sorghum genotypes were assessed for their resistance based on parameters such as Leaf Damage, Dead Heart, Tunnel length, Exit Hole and some agronomic and yield components. The results revealed varying degrees of resistance among the genotypes, providing valuable insights for breeding programs aimed at developing stem borer-resistant sorghum varieties suitable for Nigerian agro-ecosystems.
