Abstract


Fifty five isolates of Ascochyta fabae Speg. were investigated. They were selected from 1650 isolates of this fungus obtained from horse bean seeds in 1974-1976. All the isolates grew and sporulated on Potato Dextrose Agar, Malt Agar and Horse Bean Agar. The rate of their growth amounted to 1-4 mm per 24 hours. The variability of isolates in size of pycnidia and conidia and number of sepia was noticed. A few spores with untypical shapes were observed as well.
