The Natural Occurrence of Chickpea Chlorotic Dwarf Geminivirus in Chickpea and Faba Bean in the Sudan
A survey of faba bean and chickpea for virus infection, conducted during February 1994 in the Sudan, showed that bean yellow mosaic potyvirus and broad bean mottle bromovirus occurred commonly in both crops. Chickpea chlorotic dwarf geminivirus...
In this issue of Caravan, water is featured as a key item because of its importance. Water harvesting is just one aspect of improved water use. If the balance between water supply and demand cannot be put right, the consequences for food supply...
An institution such as ICARDA that aims at maintaining the high standards and dynamism of its work must have a suitable mechanism for monitoring the progress of its performance and evalu¬ating the relevance of its mandate and mission in...
Epidemiology and Geophytopathology of selected seed-borne diseases
This study in ICARDA's seed production series deals with seed-borne pathogens and their geographical distribution. It is widely acknowledged that plant diseases are one of the limiting factors in seed production, and particularly problems are...
Detection of Three Plant Viruses by Dot‐Blot and Tissue‐Blot Immunoassays Using Chemiluminescent and Chromogenic Substrates
Detection of bean yellow mosaic virus (BYMV), impatiens necrotic spot virus (INSV) and lily symptomless virus (LSV) by dot‐blot and tissue‐blot immunoenzymatic assay was compared by using either chromogenic or chemiluminescent substrates...
Pea seed-borne mosaic virus: occurrence in faba bean (Vicia faba) and lentil (Lens culinaris) in West Asia and North Africa, and further information on host range, transmission characteristics, and purification
In a survey for viruses of cultivated legumes in West Asia and North Africa, pea seed-borne mosaic virus (PSbMV) was found in faba bean, lentil and pea. Using ELISA, it was detected in 107 out of 1554 faba bean samples and 40 out of 496 lentil...
Screening techniques and sources of tolerance to extremes of moisture and air temperature in cool season food legumes
Breeding for resistance to extremes of temperature and moisture in cool season food legumes is limited by the lack of adequate screening techniques. The success of each technique depends upon the representativeness and reproducibility of the...
Plant parasitic nematodes of cool season food legumes in Syria
The survey of plant nematodes of food legumes in Syria was continued in 1984 and 1987-88. Soil and root samples were collected in the major chickpea and lentil growing areas. The most damaging nematodes were the chickpea cyst nematode...
A field experiment in Syria in 1986-1991 tested the efficacy of six four-year crop rotations for the control of Heterodera ciceri on chickpea and grasspea. Crop sequences included cultivation of non-host crops (barley and wheat) for 0, 1, 2 or 3...
