Changes in heterosis of maize (Zea mays L.) varietal cross hybrids after four cycles of reciprocal recurrent selection

Autor: Kolawole, A.O. Menkir, A. Blay, E. Ofori, K. Kling, J.G.

Two improved tropical maize composites, TZL COMP3 and TZL COMP4; representing complementary heterotic pools have been subjected to four cycles of reciprocal recurrent selection (RRS) for two decades to enhance varietal cross performance. The objectives of this study were to evaluate the effect of...

An integrated molecular and conventional breeding scheme for enhancing genetic gain in maize in Africa

Autor: Gedil, M. Menkir, A.

Maize production in West and Central Africa (WCA) is constrained by a wide range of interacting stresses that keep productivity below potential yields. Among the many problems afflicting maize production in WCA, drought, foliar diseases, and parasitic weeds are the most critical. Several decades ...

Genetic gains in grain yield of a maize population improved through marker assisted recurrent selection under stress and non-stress conditions in west Africa

Autor: Abdulmalik, R.O. Menkir, A. Meseka, S.K. Unachukwu, N.N. Ado, S.G. Olarewaju, J.D. Aba, D.A. Hearne, S. Crossa, J. Gedil, M.

Marker-assisted recurrent selection (MARS) is a breeding method used to accumulate favorable alleles that for example confer tolerance to drought in inbred lines from several genomic regions within a single population. A bi-parental cross formed from two parents that combine resistance to Striga ...

Genetic gains in yield and yield related traits under drought stress and favorable environments in a maize population improved using marker assisted recurrent selection

Autor: Bankole, F. Menkir, A. Olaoye, G. Crossa, J. Hearne, S. Unachukwu, N.N. Gedil, M.

The objective of marker assisted recurrent selection (MARS) is to increase the frequency of favorable marker alleles in a population before inbred line extraction. This approach was used to improve drought tolerance and grain yield (GY) in a biparental cross of two elite drought tolerant lines. T...

Accruing genetic gain in pro-vitamin A enrichment from harnessing diverse maize germplasm

Autor: Menkir, A. Maziya-Dixon, B.B. Mengesha, W. Rocheford, T. Alamu, E.O.

Maize has been targeted as one of the major crops for provitamin enrichment and delivery because it is an inexpensive and easily available source of food for millions of people in sub-Saharan Africa. Although tropical-adapted yellow maize contains provitamin-A carotenoids that can be converted in...
