Badu-Apraku, B.Menkir, A.Fakorede, M.A.B.Ajala, S.O.Ellis-Jones, J.[Building partnerships and encouraging innovation for sustainable maize production: the West and Central Africa Collaborative Maize Research Network, achievements and impact]Building partnerships and encouraging innovation for sustainable maize production: the West and Central Africa Collaborative Maize Research Network, achievements and impact

Increase in maize grain yield in West Africa can be achieved by developing maize varieties tolerant to low soil nitrogen (N) and improving soil fertility. Six maize populations were evaluated in two locations in Nigeria under low-N (45 kg N ha−1) and high-N (90 kg N ha−1) conditions to identify m...

Maize researchers in West and Central Africa (WCA) established the West and Central Africa Collaborative Maize Research Network (WECAMAN) in 1987 to tackle maize production constraints too formidable for individual national programs to overcome. The National Agricultural Research Systems (NARS) t...


Fakorede, M.A.B.Badu-Apraku, B.Menkir, A.Ajala, S.O.Lum, A.F.[A review of NARES-IARC-Donor collaboration to develop demand-driven technologies for improved maize production in West and Central Africa]A review of NARES-IARC-Donor collaboration to develop demand-driven technologies for improved maize production in West and Central Africa

Advanced rice breeding lines were evaluated in eight environments (two seasons and four N-fertilizer levels) to investigate the effectiveness of selecting genotypes for less favorable low fertilizer input environments. Highly significant Environment (E), Genotype (G) and G x E. interaction effect...

A maize population was subjected to three different selection procedures to determine the best methodfor its improvement in a study conducted at Ibadan, Nigeria. Considerable genetic variability existedwithin the population for effective selection for each of the traits considered, using any of t...


Ajala, S.O.Ago, C.E.Olaoye , G.[Comparison of predicted responses to three types of recurrent selection procedures for the improvement of a maize (Zea mays L.) population]Comparison of predicted responses to three types of recurrent selection procedures for the improvement of a maize (Zea mays L.) population

Genetic diversity that can be profitably exploited is a major desire of several maize (Zea mays L.) breeding programs. The objective of this study was to identify maize populations that could be used in reciprocal recurrent selection programs for combined resistance to two stem borers, Sesamia ca...


Ajala, S.O.Odiyi, A.C.The, C.Olaoye, G[Population cross diallel of maize genotypes with varying levels of resistance to the pink stalk borer (Sesamia calamistis: Hampson) and the sugarcane borer (Eldana sacharina: Walker)]Population cross diallel of maize genotypes with varying levels of resistance to the pink stalk borer (Sesamia calamistis: Hampson) and the sugarcane borer (Eldana sacharina: Walker)

Low soil nitrogen (low N) limits maize (Zea maysL.) production in sub-Saharan Africa (SSA). Knowledge of inheritance of tolerance to low N in inbred lines selected for drought tolerance would be useful for developing hybrids adapted to low N conditions. The objectives of this study were to determ...


Meseka, S.K.Menkir, A.Ibrahim, A.E.Ajala, S.O.[Genetic analysis of performance of maize inbred lines selected for tolerance to drought under low nitrogen]Genetic analysis of performance of maize inbred lines selected for tolerance to drought under low nitrogen

Grain yield of maize (Zea mays L.) in the tropics are generally low and information on combining ability among tropical maize inbred lines has not been reported for West Africa. This study was conducted to estimate combining abilities of maize inbred lines developed for West Africa. Crosses obtai...
