Journal Article 2011

Gene flow among different teosinte taxa and into the domesticated maize gene pool

Autor: Warburton, M.L. Wilkes, G. Taba, S. Charcosset, A. Mir, C. Dumas, F. Madur, D. Dreisigacker, S. Bedoya, C. Prasanna, B.M. Xie, C.X. Hearne, S. Franco, J.

Maize (Zea mays L. ssp. mays) was domesticated from one wild species ancestor, the Balsas teosinte (Zea mays ssp. parviglumis) about 9000 years ago. Higher levels of gene diversity are found in teosinte taxa compared to maize, following domestication and selection bottlenecks. Diversity in maize ...

A detached leaf assay to rapidly screen for resistance of maize to Bipolaris maydis, the causal agent of southern corn leaf blight

Autor: Aregbesola, E. Ortega-Beltran, A. Falade, T. Jonathan, G. Hearne, S. Bandyopadhyay, R.

Southern corn leaf blight (SCLB), caused by the fungus Bipolaris maydis, is a disease that significantly affects maize productivity across the globe. A detached leaf assay (DLA) was developed to rapidly assess maize resistance to SCLB. Several experiments were conducted to: (i) identify a highly ...

Relationships between normalized difference vegetation index (NDVI) and other traits of tropical testcross maize (Zea mays L.) hybrids under drought and wellwatered conditions

Autor: Adebayo, M.A. Menkir, A. Hearne, S.

Normalized difference vegetation index (NDVI) is a non-destructive measure of green vegetation growth or above ground biomass of a crop. NDVI may also be used to evaluate traits such as early vigour and stay green which are important for adaptation to drought stress. In the present study, the rel...

Genetic analysis of drought tolerance in adapted X exotic crosses of maize inbred lines under managed stress conditions

Autor: Adebayo, M.A. Menkir, A. Blay, E. Gracen, V.E. Danquah, E.Y. Hearne, S.

Abstract Introduced maize (Zea mays L.) germplasmcan serve as sources of favorable alleles toenhance performance in new maize varieties andhybrids under drought stress conditions. In the presentstudy, the combining abilities of 12 exotic maizeinbred lines from CIMMYT and 12 adapted maizeinbred li...

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...

Genetic diversity of tropical early-maturing maize inbreds and their performance in hybrid combinations under drought and optimum growing conditions

Autor: Oyekunle, M. Badu-Apraku, B. Hearne, S. Franco, J.

Hybrid development is enhanced by the assessment and understanding of genetic diversity and distance within inbreds. One hundred and fifty hybrids derived from 30 early-maturing inbreds plus six checks were evaluated at three locations in Nigeria for 2 years to assess their performance under drou...
