Abstract

On September 2001 a survey of lodged maize (Zea mays L.) plants to identify the main root rot pathogens related to maize lodging was carried out in 23 cornfields of Abegondo (A Coruña, Spain). From 328 maize plants showing lodging, 33 isolates of the following potential maize pathogens were collected: Fusarium semitectum Berk&Rav., F. graminearum Schwabe, F. culmorum (W. Smith) Sacc., F. solani Appel&Wall and F. moniliforme Sheldon. The inoculation of four strains of F. moniliforme, three of F. graminearum, one of F. culmorum and one of F. semitectum on two maize inbreds with different susceptibility to lodging EC23D and EC136 as susceptible and resistant inbreds respectively showed F. graminearum Schwabe as the most pathogenic fungus considering either root rot symptom or seedling growth reduction. The importance of considering the susceptibility to root rot pathogens in maize breeding programs for resistance to lodging is also discussed.
