摘要：
The genetic variability of 22 isolates of the fungi Alternaria alternata and A. cassiae, obtained from Senna obtusifolia, was studied by RAPD analysis. A total of 491 scorable bands were produced with the use of 28 primers. Cluster analysis based on similarities computed from RAPD markers showed two distinct genetic groups of isolates related to both species. RAPD analysis proved to be an efficient method for detecting genetic variability of A. cassiae and A. alternata isolates occurring in S. obtusifolia, and also for distinguishing Alternaria species.
