Relationships between Stalk Resistance and Corn Borers, Agronomic Traits, and Cell Wall Hydroxycinnamates in a Set of Recombinant Inbred Lines from a Maize MAGIC Population

Corn borers are the most important pest affecting maize. Resistance to corn borer attack may compromise plant fitness being detrimental for some agronomic traits such as yield. Against of this pest, cell wall-bound hydroxycinnamates have been previously described a possible defense mechanism. In study, characterization and quantification was performed in subset Recombinant Inbred Lines (RILs) from Multiparent Advanced Generation Intercross (MAGIC) population that showed contrasting behavior against attack. Resistant lines greater concentration p-coumaric acid, only hydroxycinnamate could role resistance these particular materials. addition, results indicated resistant precocity, low grain moisture at harvest, reduced height, thus, selecting be way, breeding strategy directly targeting yield order tolerate would recommended one.
