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...
Water-use efficiency and transpiration efficiency of wheat under rain-fed conditions and supplemental irrigation in a Mediterranean-type environment
Growth and water use were measured in wheat (Triticum aestivum L.) grown in northern Syria in a typical Mediterranean climate over five seasons 1991/92-1995/96. Water use was partitioned into transpiration (T) and soil evaporation (E-s) using...
Read in this issue: a) Poverty—it is also rural, and it is connected with agriculture. And it is perhaps the biggest single threat to the environment in dry areas. b) Central Asian agriculture is changing. ICARDA is now the focal point for...
The year 1997 marked a significant milestone in ICARDA's history, celebrating the Center's 20th anniversary. It was a time to reflect on past achievements and look forward to the future. One of ICARDA's most notable accomplishments over the past...
Italy has a long historical connection with ICARDA and has been instrumental in much of the Center's genetic-resources activities. The Italian Government supported the establishment of a modem gene bank which has facilities for medium- and long...
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...
