A participatory farming system approach for sustainable broomrape (Orobanche spp.) management in the Near East and North Africa
Broomrapes (Orobanche spp.) are aggressive and damaging parasitic weeds which have a tremendous impact on agriculture in East Africa, the Mediterranean region and the Middle East. Despite the availability of technologies ...
Capturing the Heterogeneity of the Error Variances of a Group of Genotypes in Crop Cultivar Trials
Appropriate experimental designs provide an efficient estimate of cultivar performance by allowing better control of experimental error. The standard approach assumes homogeneity of experimental error variances across ...
ICARDA Efforts to Promote In Situ/On-farm Conservation of Dryland Agrobiodiversity
Dryland biodiversity has only recently got due attention because of its potential to contribute in overcoming the effects of global challenges caused by land degradation and and climate change (FAO, 1989). More particularly, ...
Adaptation and Stability Analysis of ICARDA Durum Wheat Elites across 18 Countries
Durum wheat (Triticum durum Desf.) is the 10th most important crop in the world, and its cultivation occurs on a vast array of international agroenvironments. However, its wide international adaptation is only marginally ...
The potential of small-scale rainfed agriculture to strengthen food security in Arab countries
In most Arab countries, domestic agricultural production is insufficient. The gap between production and demand is likely to increase due to climate change and other factors. This review paper examines the challenges and ...
Some characteristics of Rhizobium leguminosarum isolates from uninoculated field-grown lentil
A total of 229 Rhizobium leguminosarum isolates from the lentil-growing region of West Asia-North Africa (WANA) were evaluated for their symbiotic effectiveness and for salt and heat tolerance. These included 65 isolates ...
Evidence for genotypic differences among elite lines of common bean in the ability to remobilize photosynthate to increase yield under drought
Common bean (Phaseolus vulgaris L.) is the most important food legume for human consumption. Drought stress is the major abiotic stress limitation of bean yields in smallholder farming systems worldwide. The current work ...
Molecular characterization of faba bean necrotic yellows viruses in Tunisia
Faba bean necrotic yellows virus (FBNYV) (genus Nanovirus; family Nanoviridae) has a genome comprising eight individually encapsidated circular single-stranded DNA components. It has frequently been found infecting faba ...
Food Security and Water Poverty in Central and West Asia and North Africa Region
ll countries in Central and West Asia and North Africa (CWANA) region in general, and the WANA region in particular, have faced severe challenges in increasing their agricultural production over the last 40 years. This is ...
Genetic diversity and structure in Egyptian indigenous sheep populations mirror patterns of anthropological interactions
Human exchange networks are instrumental in influencing gene flow among domesticates. Here, we investigated levels of within- and between-population genetic diversity in 289 animals from six indigenous sheep populations ...
