Dissecting genome-wide association signals for loss-of-function phenotypes in sorghum flavonoid pigmentation traits
(Genetics Society of America, 2013)
Genome-wide association studies (GWAS) are a powerful method to dissect the genetic basis of traits, though in practice the effects of complex genetic architecture and population structure remain poorly understood. To ...
Reconstituting family transitions of Sahelian western Niger 1950-2000: an agent-based modelling approach in a low data context
(Cybergeo : European Journal of Geography, 2013)
This research analyses the impacts of the family organization on the diversity of income sources and the sustainability and the dynamics of rainfed farming systems of Sahelian Niger, through an individual-centred agent-based ...
Conservation agriculture systems for Malawian smallholder farmers: long term effects on crop productivity, profitability and soil quality
(Cambridge University Press, 2013)
Conservation agriculture (CA) systems are based upon minimal soil disturbance; crop residue retention and crop rotation and/or intercrop association are increasingly seen to recycle nutrients, increase yield and reduce ...
Identificacion de razas mexicanas de maiz adaptadas a condiciones deficientes de humedad mediante datos biogeograficos
Se trabajo con una base de datos de accesiones recientes de 54 razas de maíz de México, cuyos datos pasaporte se extrajeron de la Unidad de Recursos Geneticos del Banco de Germoplasma del INIFAP. A partir de las coordenadas ...
Wheat crop response to liming materials and N and P fertilizers in acidic soils of Tsegede highlands, northern Ethiopia
(Science Publishing Group, 2013)
A greenhouse experiment was carried out on acidic soils collected from the Tsegede highlands of northern Ethiopia, where wheat production is severely constrained by soil acidity, to evaluate wheat crop response to the ...
Beyond climate-smart agriculture: toward safe operating spaces for global food systems
(BioMed Central, 2013)
Agriculture is considered to be "climate-smart" when it contributes to increasing food security, adaptation and mitigation in a sustainable way. This new concept now dominates current discussions in agricultural development ...
Evaluation of three field-based methods for quantifying soil carbon
(Public Library of Science, 2013)
Three advanced technologies to measure soil carbon (C) density (g C m−2) are deployed in the field and the results compared against those obtained by the dry combustion (DC) method. The advanced methods are: a) Laser ...
Genetic diversity and molecular evolution of chinese waxy maize germplasm
(Public Library of Science, 2013)
Waxy maize (Zea mays L. var. certaina Kulesh), with many excellent characters in terms of starch composition and economic value, has grown in China for a long history and its production has increased dramatically in recent ...
Spatial analysis to support geographic targeting of genotypes to environments
Crop improvement efforts have benefited greatly from advances in available data, computing technology, and methods for targeting genotypes to environments. These advances support the analysis of genotype by environment ...
Crops that feed the world 10. Past successes and future challenges to the role played by wheat in global food security
(Springer Verlag, 2013)
Wheat is fundamental to human civilization and has played an outstanding role in feeding a hungry world and improving global food security. The crop contributes about 20 % of the total dietary calories and proteins worldwide. ...
