Novel QTLs in an interspecific backcross Oryza sativa�נOryza glaberrima for resistance to iron toxicity in rice
Department for International Development (DFID)
Abstract
Iron (Fe) toxicity is a major constraint in lowland rice. Because of its higher rusticity and adaptability to adverse soil conditions, the African rice Oryza glaberrima constitutes a new potential source of genes for rice improvement.This study aimed at mapping quantitative trait loci (QTLs) for resistance to Fe toxicity. A set of 220 BC3DH lines derived from the…

A universal core genetic map for rice
Department for International Development (DFID)
Abstract
To facilitate the creation of easily comparable, low-resolution genetic maps with evenly distributed markers in rice (Oryza sativa L.), we conceived of and developed a Universal Core Genetic Map (UCGM). With this aim, we derived a set of 165 anchors, representing clusters of three microsatellite or simple sequence repeat (SSR) markers arranged into non-recombining groups. Each anchor consists of at least three, closely linked SSRs, located…

Cropland
Center for International Forestry Research (CIFOR)
Abstract
Carbon can be stored in the biomass of croplands that contain perennial woody vegetation including, but not limited to, monocultures such as tea, coffee, oil palm, coconut, rubber plantations, fruit and nut orchards, and polycultures such as agroforestry systems. The default methodology for estimating carbon stock changes in woody biomass is provided in Chapter 2, Section 2.2.1. This section elaborates this methodology with respect to estimating changes in carbon…

Interactive effects of altitude, microclimate and shading system on coffee leaf rust
International Institute of Tropical Agriculture (IITA)
Abstract
Shade effects on coffee diseases are ambiguous because they vary depending on the season and environment. Using Coffee Leaf Rust (CLR) as an example, we demonstrate relationships between the environment and shading systems and their effects on disease intensity. We characterized seasonal variations in microclimate and CLR incidence across different altitudes and shading systems, and…

Varietal Generation and Output
International Center for Agricultural Research in the Dry Areas (ICARDA)
Abstract
This chapter focuses on the improved cultivar generation of various crops (maize, cassava, rice, bean, potato, cowpea, wheat, soyabean, sweet potato, yam, sorghum, groundnut, banana, chickpea, pigeon pea, barley, pearl millet, faba bean, lentil and pea) in Africa South of the Sahara. Information of cultivar output of these crops is also pressented

ECOREGIONAL RESEARCH IN AFRICA: LEARNING LESSONS FROM IITA'S BENCHMARK AREA APPROACH
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
Ecoregional research has the potential to help address some of the huge challenges facing agriculture in developing countries by developing technologies that work under different agro-ecological conditions, and the processes by which these technologies can be adapted to work in other areas with similar conditions. The CGIAR system has been developing ecoregional…

QTL Analysis of Seed Iron, Zinc, and Phosphorus Levels in an Andean Bean Population
Department for International Development (DFID)
Abstract
Iron and zinc are essential micronutrients for human health often found in insufficient quantities in the diet. Biofortification of seed crops has been undertaken to reduce micronutrient malnutrition. The objectives of this study were to identify variability for seed Fe, Zn, P, and phytic acid levels in an F5:7 recombinant inbred line (RIL) population developed from a cross between AND696 and…

Implications of a changing climate on food security and smallholders? livelihoods in Bogot�, Colombia
Department for International Development (DFID)
Abstract
Small farmers who supply the city of Bogotá with food are facing many challenges that are jeopardizing their livelihoods and by extension, the food security of Colombia�??s capital. We expect future changes in climatic conditions to exacerbate the plight of the small farmers and this is expected to compromise Bogota�??s food security even further. This paper specifically seeks…

Generic methodologies applicable to multiple land-use categories
World Agroforestry Centre (ICRAF)
Abstract
Methods to estimate greenhouse gas emissions and removals in the Agriculture, Forestry and Other Land Use (AFOLU) Sector can be divided into two broad categories: 1) methods that can be applied in a similar way for any of the types of land use (i.e., generic methods for Forest Land, Cropland, Grassland, Wetlands, Settlements and Other Land); and 2) methods that only apply to a single land use or that are applied to aggregate…
