The challenges in the dry areas are many and varied in their intensity to constrain agriculture for the resource-poor farmer. Underlying these challenges is, however, a common factor—water, or at least scarcity of this precious commodity. It is...
Management alternatives for improved durum wheat production under supplemental irrigation in Syria
In the Mediterranean zone, efforts to optimize combinations of supplemental irrigation (SI), improved varieties, nitrogen (N) and sowing dates aim to improve and stabilize cereal yields and maintain quality, especially for durum wheat. Thus, a 4...
Survey for chickpea and lentil virus diseases in Ethiopia
Chickpea (Cicer arietinum L.) and lentil (Lens culinaris Medik.) are among the major cool-season food legumes grown in Ethiopia. Fungal and viral diseases are important factors limiting production of these two crops in the Country. As there is...
Inheritance and Linkage Analysis of Frost Injury in Lentil
Radiation-frost injury is an important abiotic constraint to lentil (Lens culinaris Medik.) production in West Asia, but no information has been published on the inheritance of radiation-frost injury in lentil. The objectives of the study were...
Inheritance and linkage relationships of days to flower and morphological loci in lentil (Lens culinaris Medikus subsp. culinaris)
Lentils from south Asia differ markedly in days to flower and several other traits from lentils in other major lentil producing areas of the world such as west Asia. Single-gene inheritance and a polygenic system were observed to control days to...
Caravan 10 : Review of agriculture in the dry areas
This issue of Caravan will provide a glimpse of the holistic approach that ICARDA is employing to achieve increased efficiency in food production from the dry, marginal areas.
Identification in Aegilops species of resistant sources to Hessian fly (Diptera: Cecidomyiidae) in Morocco
Hessian fly, Mayetiola destructor (Say), is the major insect pest of wheat in Morocco. Host plant resistance has been the most effective and practical method of controlling this pest. When 347 accessions of Aegilops species were screened in the...
A genetic linkage map of lentil (Lens sp.) based on RAPD and AFLP markers using recombinant inbred lines
A genetic linkage map of Lens sp. was constructed with 177 markers (89 RAPD, 79 AFLP, six RFLP and three morphological markers) using 86 recombinant inbred lines (F-6:8) Obtained from a partially interspecific cross. The map covered 1073 cM of...
This issue of Caravan, presents a few examples of the harmony of ICARDA research with nature. The collaborative long-term trials in Egypt have produced tentative guidelines which will help farmers to use less water, and fewer external inputs(and...
