BACKGROUND Ostrinia nubilalis (ECB) and Sesamia nonagrioides (MCB) are two maize stem borers which cause important losses in temperate maize production, but QTL analyses for corn borer resistance were mostly restricted to ECB resistance and maize materials genetically related (mapping populations derived from B73). Therefore, the objective of this work was(More)
Reciprocal recurrent selection (RRS) was proposed for simultaneously improving two populations and their cross. A modification of the classical full-sib RRS (FS-RRS) was proposed in which the performance of full-sibs and S2 families is combined in a selection index (FS-S2-RRS). The Mediterranean corn borer (MCB) is the main corn borer species in the(More)
The Mediterranean corn borer (MCB) is the most important maize insect pest in the Mediterranean region. The main objective was to map quantitative trait loci (QTL) for yield performance under infestation with MCB, resistance and agronomic traits in a maize RIL population derived from an inbred cross European flint × Reid. Six QTL for resistance traits were(More)
Agronomic evaluations demonstrated that a modification of the classical full-sib reciprocal recurrent selection (RRS-FS) which, in addition to crosses, uses S2 families evaluation (RRS-FS-S2) is more efficient than the classical method for developing high-yielding crosses between two varieties. The objective of this study was to investigate the changes in(More)
