Vitamin A deficiency, drought, low soil nitrogen (low N) and Striga hermonthica parasitism of maize (Zea mays L.) cause malnutrition and food insecurity in sub-Saharan Africa. The objectives of this study were to determine combining abilities of extra-early provitamin A (PVA) lines, classify them...

Genetic studies of extra-early provitamin-A maize inbred lines and their hybrids in multiple environments
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...

Screening maize for drought tolerance in the Guinea savanna of West and Central Africa
Maize (Zea mays L.) landraces in the northern Guinea savanna and Sudan savanna in West and Central Africa appear to have some drought-adaptive traits. This study was initiated to assess the level of improvement in yield potential and other agronomic traits achieved under drought stress (DS) and i...

Introgression of alleles from maize landraces to improve drought tolerance in an adapted germplasm
Maize (Zea mays L.) is the most important staple crop in West and Central Africa (WCA), but its production is severely constrained by low soil nitrogen (low N). Fifty-six extra-early open-pollinated maize cultivars developed during three breeding eras, 1995–2000, 2001–2006 and 2007–2012, were eva...

Improvement in grain yield and low-nitrogen tolerance in maize cultivars of there eras
Maize hybrids that are tolerant to drought at the seedling stage are needed to boost productivity in the rainforest agro-ecology of West Africa. Genetics of tolerance of maize seedling to drought stress is not well understood and is poorly documented. The objectives of this study were to screen e...

Genetic gains in grain yield under nitrogen stress following three decades of breeding for drought tolerance and Striga resistance in early maturing maize
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...

Striga and drought are major constraints to
maize (Zea mays L.) production in the savannas
of west and central Africa (WCA). A study
was conducted in 2005 and 2006 in Nigeria to
determine the level of resistance to Striga hermonthica
for two early-maturing maize populations,
one white and one yel...

Background
Maize yield potential is rarely maximized in sub-Saharan Africa (SSA) due to the devastating effects of drought stress and Striga hermonthica parasitism. This study was conducted to determine the gains in grain yield and associated changes in an early-maturing yellow bi-parental maize ...
