Improving Water Productivity in the Dry Areas of West Asia and North Africa
In the dry areas, water, not land, is the limiting factor in improving agricultural production. Maximizing water productivity, and not yield per unit of land, is therefore a better strategy for on-farm water man- agement under such conditions...
Genetic dissection of pathotype-specific resistance to ascochyta blight disease in chickpea (Cicer arietinum L.) using microsatellite markers
Ascochyta blight is an economically important disease of chickpea caused by the fungus Ascochyta rabiei. The fungus shows considerable variation for pathogenicity in nature. However, studies on the genetics of pathotype-specific resistance are...
This issue of Caravan presents the facts about drought, including efforts to more accurately predict its occurrence and severity. Agroclimatologists, for example, are making use of satellite imagery and geographical information systems in their...

First record of Beet western yellows virus, Chickpea chlorotic dwarf virus, Faba bean necrotic yellows virus and Soybean dwarf virus infecting chickpea and lentil crops in Iran
An intensive survey was conducted during May–June, 2001 to identify virus diseases affecting chickpea (Cicer arietinum) and lentil (Lens culinaris) crops in five provinces (Qazvin, Kermanshah, Kurdistan, East Azarbaijan and West Azarbaijan) of...
Segregation distortion in doubled haploid lines of barley (Hordeum vulgare L.) detected by simple sequence repeat (SSR) markers
A total of 147 simple sequence repeat (SSR) markers (including86 barley and 61 wheat microsatellite markers) were tested for their segregation in a doubled haploid (DH) and an F2 population of barley. The DH population consisted of 71 doubled...
Opuntias are multipurpose plants that are increasingly being used in agricultural systems in arid and semi-arid areas and are considered a key component for the productivity and sustainability of these regions. This publication presents current...
Comparison of European with West Asian and North African winter barleys in tolerance to boron toxicity
Three plastic-house experiments were conducted to compare the tolerance of European with West Asian and North African (WANA) winter barleys to boron (B) toxicity. Experiment I screened 24 winter barley entries with diverse origins. Experiment...
