Multi-environment trials (METs) in West Africa have demonstrated the existence of genotype×environment interactions (G×E), which complicate the selection of superior cultivars and the best testing sites for identifying superior and stable genotypes. Two powerful statistical tools available for ME...

Performance of extraearly maize cultivars based on GGE biplot and AMMI analysis
Recurrent selection under artificial S. hermonthica infestation has significantly reduced the number of emerged Striga plants and increased grain yield under Striga infestation in broad-based populations. These populations have been sources of varieties and inbred lines with consistently high lev...

Maize (Zea mays) is a staple food crop in sub-Saharan Africa, but itsproduction is threatened byStriga hermonthica(Del.) Benth. Transferof resistance genes from wild relatives may increase resistance toS. hermonthicain tropical maize. The objective of this study was todetermine the combining abil...
Availability of extra-early maize cultivars has facilitated the expansion of maize production into savannas of West and Central Africa (WCA). Fifty-six extra-early maize cultivars of three breeding eras;1995 to 2000, 2001 to 2006, and 2007 to 2012 were evaluated for 2 yr under 24 multiple-stress ...

An extra-early maturing white-grained, flint/dent maize (Zea mays L.) population, TZEE-W Pop STR C4 (Reg. No. GP-576; PI 657704), has been developed at the International Institute of Tropical Agriculture. The population has moderate levels of resistance to Striga hermonthica (Del.) Benth. It was ...
