The use of Rapd markers for lentil genetic mapping and the evaluation of distorted F2 segregation
To maximize the extent of polymorphism within a mapping population wide crosses are often made, frequently resulting in distorted segregation. Two parents used in the crosses in this study contained ca 50% from wild lentil genome (Lens culinaris...

Screening and selection of faba bean (Vicia faba L.) germplasm for resistance to bean yellow mosaic potyvirus
Six hundred and five faba bean genotypes were evaluated for their reaction to a Syrian isolate (SV205-85) of bean yellow mosaic potyvirus (BYMV). The preliminary evaluation of the different genotypes response to infection was conducted under...
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...
