Genetic analysis of drought tolerance in maize inbred lines: preliminary results

Autor: Meseka, S.K. Menkir, A. Ibrahim, A.

Drought stress causes significant yield reduction in maize Zea mays L. grown in sub-Saharan Africa (SSA. An understanding of the inheritance of drought tolerance would be useful in developing drought tolerant hybrids. The objectives of this study were to determine (i) the effects of the level of ...

Novel sources of resistance to Fusarium stalk rot of maize in tropical Africa

Autor: Afolabi, C.G. Ojiambo, P.S. Ekpo, E.J. Menkir, A. Bandyopadhyay, Ranajit

Fusarium stalk rot is one of the most widespread and destructive diseases of maize, and deployment of resistant genotypes is one of the most effective strategies for controlling the disease. Fifty inbred lines and four checks from the breeding program of the International Institute of Tropical Ag...

Response to recurrent selection for resistance to Striga hermonthica (Del.) Benth in a tropical maize population

Autor: Menkir, A. Kling, J.

Striga hermonthica (Del.) Benth is an obligate root parasite infecting maize (Zea mays L.) and causing considerable yield losses in Africa. Few studies have been conducted to determine the effectiveness of recurrent selection for improving resistance to S. hermonthica in maize. The objective of t...

Assessment of testcross performance and genetic diversity of yellow endosperm maize lines derived from adapted x exotic backcrosses

Autor: Menkir, A. Olowolafe, M.O. Ingelbrecht, I.L. Fawole, I. Badu-Apraku, B. Vroh Bi, Irie

Introduction of exotic maize (Zea mays L.) into adapted tropical germplasm may enhance genetic variability and lead to greater progress from selection. The first objective of this study was to determine if yellow endosperm lines derived from adapted x exotic backcrosses contain exotic alleles tha...

Performance of tropical early maturing maize cultivars in multiple stress environments

Autor: Badu-Apraku, B. Menkir, A. Ajala, S. Akinwale, R. Oyekunle, M. Obeng-Antwi, K.

Maize (Zea mays L.) production in west Africa (WA) is constrained by drought, Striga hermonthica infestation and low soil nitrogen (N). Maize varieties resistant to Striga, drought, and low N are ideal for WA, but genotype × environment interaction on these traits are usually significant due to d...
