AB  - <I>Alternaria solani </I>is known economically important and 
  the casual agent of early blight on potato and tomato. Identification of plant 
  pathogens is very important in helping to find effective disease control or 
  management methods. Morphology and physiology characteristics of <I>Alternaria 
  solani</I> were investigated for identification and variability. The optimum 
  pH levels of <I>Alternaria solani</I> grow <I>in vitro</I> were 6-7 and the 
  optimum growing temperatures of the isolates recovery in this study was 25 and 
  30&deg;C. The mycelial width between 0.8-1.5 &#956;m and the conidia are 35-75 
  &#956;m in length and 10-20 &#956;m in width and 2-7 transverse septa and 1-4 
  longitudinal septa. This study pointed that there was a variation in the population 
  of <I>Alternaria solani</I> isolated from Jordan valley based on morphology 
  and physiology characteristics.
