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...
At ICARDA, 1992 was a year of review, self-searching and planning for the future, which culminated in the preparation of a Medium-term Plan for the period 1994-98. The Plan was developed in the context of major developments in ICARDA's external...
