title: In VitroMorphological Characteristics ofPyrenophora tritici-repentisIsolates from Several Algerian Agro-Ecological Zones.
abstract: Tan spot caused by the fungusPyrenophora triticirepentisis a serious disease of wheat, which is on increase in recent years in Mediterranean region. In the field this fungus produces a diamond-shaped necrotic lesions with a yellow halo on wheat foliage. The objective of this study was to characterize and compare several monospore isolates ofP. tritici-repentiscollected from different infected wheat fields in various locations of Algeria, and find the morphological differences between them, if any. The results revealed wide morphologically variation among the isolates based on colony colors and texture, mycelial radial growth and conidial size.
