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 ...
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 ...
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 ...
Variation in soil chemical properties along toposequences in an arid region of the Levant
Detailed characterization of soils and their variation along different topography positions has not been investigated in depth for Mediterranean arid regions. There is a need to accurately understand the variation and the ...
A Multivariate Analysis of Factors Affecting Adoption of Improved Varieties of Multiple Crops: A Case Study from Ethiopian Highlands
This paper analyzes the synergies/tradeoffs involved in the adoption of improved varieties of
multiple crops in the mixed crop-livestock production systems of the highlands of Ethiopia A
multivariate probit (MVP) model ...
Genetic diversity and structure of goats within an early livestock dispersal area in Eastern North Africa
In this study we genotyped 14 microsatellites to assess genetic diversity, population stratification and demographic dynamics using Egyptian local goats (Zaraibi, Baladi, Saidi and Barki) and the Shami (Damascus) goat from ...
