Secondary traits can improve precision with which drought or low soil nitrogen (low-N) tolerant maize (Zea mays L.) genotypes are identified, compared to measuring only grain yield under each stress. The objective of this study was to identify secondary traits for indirect selection for yield imp...

Full-sib families derived from Pool 16 DT, a tropical maize ( Zea mays L.) population, were evaluated in the 1995/96 and 1997/98 dry seasons, using two sites each season in Côte d’Ivoire. In all sites, the crop was irrigated from planting to about 2 weeks before anthesis, irrigation was discontin...

North Carolina Design I (NCD I) progenies derived from Pool 16 DT, a white, dent, early maturing, drought-tolerant and streak resistant tropical maize (Zea mays L.) population, were evaluated in the 1995/96 and 1997/98 dry seasons, using two sites each season in Côte d'Ivoire. In all sites, the c...

Emergence of several seed companies in the West Africa sub-region during the last decade has necessitated intensified efforts towards hybrid development and extensive testing. The objectives of the present study were to evaluate selected Striga-resistant maize (Zea mays L.) hybrids for grain yiel...

Two major constraintsmilitatingagainst the achievement of food security in West Africa (WA) are recurrent drought and poor soil fertility. Seventeen early maturing maize inbreds from IITA and CIMMYT were used as parents to produce 136 diallel crosses which were evaluated along with four checks in...
