Fusarium oxysporum f. sp. albedinis (FOA) is a seed- and soil-borne vascular wilt pathogen that causes a very serious and destructive disease of date palm (Bayoud disease). FOA is not currently known to occur in Saudi Arabia, but the disease has been moving eastward from its origin in Morocco and Algeria. The main objective of this study was to evaluate Saudi Arabian date palm germplasm at the molecular level to assess the presence of R or S plasmid.

Fusarium is one of the most destructive fungal genera whose members cause many diseases on plants, animals, and humans. Moreover, many Fusarium species secrete mycotoxins (e.g. trichothecenes and fumonisins) that are toxic to humans and animals. Fusarium isolates from date palm trees showing disease symptoms, e.g. chlorosis, necrosis and whitening, were collected from seven regions across Saudi Arabia. After single-sporing, the fungal strains were morphologically characterized.

The question of whether the adaptability and production performance in goats may be enhanced using a crossbreeding program between bucks of a native and heat-tolerant breed and does of an exotic and dual-purpose breed was approached and examined herein by comparing purebred Aardi and Damascus goats and their crossbred lines (i.e., 1/2 Aardi 1/2 Damascus (½A½D) and 1/4 Aardi 3/4 Damascus (¼A¾D)) reared in a region characterized by dry and hot
bioclimatic conditions. Twenty-four male 6-month-old kids randomly segregated into four groups (six replicates/group)
