Heterotic Effects and Association of Chilo partellus (Swinhoe) Resistance Parameters with Mature Plant Traits in some Maize Populations

Stem borer resistance and grain yield are known to be quantitatively inherited, but it is not known whether the heterotic levels observed for resistance are translated directly to grain yield production. Results of correlations between vigour associated with resistance and that of mature plant trait...

Summary:Stem borer resistance and grain yield are known to be quantitatively inherited, but it is not known whether the heterotic levels observed for resistance are translated directly to grain yield production. Results of correlations between vigour associated with resistance and that of mature plant traits suggest that, although most of the crosses had lower damage levels and increased grain yield, the vigour associated with resistance traits may not actually predict the amount of grain yield gain obtained in the set of maize genotypes studied.
