“…Of the genotypes that stood out for SCB resistance, hybrid AF-28 is known for possessing multiple insect resistance; in addition to SCB, the hybrid shows resistance to sorghum midge, Stenodiplosis (=Contarinia) sorghicola (Coquillet) (Diptera: Cecidomyiidae), and corn aphid, Rhopalosiphum maidis (Fitch) (Hemiptera: Aphididae). However, hybrid AF-28 exhibits undesirable agronomic characteristics, such as late development and non-erect formation (Rossetto et al, 1976;Boiça Júnior and Lara, 1983;Rossetto and Igue, 1983;Lara and Perussi, 1984;Lara et al, 1997). Therefore, evaluations of different genetic materials should not only take into account the resistance to the pest in question but should also consider other plant parameters, which can result in the identification of genotypes with all desired characteristics for cost-effective grain production.…”
