Isolates of Bipolaris victoriae were analysed by
random amplified polymorphic DNA (RAPD) techniques to
determine the amount of intraspecific genetic variability.
Seven primers were applied and DNA bands of 200-5000 bp were
produced. Cluster analysis using UPGMA method gave five
groups. Levels of polymorphism were observed between DNA of
different isolates. The pattern of RAPD bands did not show
any correlation between polymorphism and climates or
geographical areas.
Key words:
Bipolaris victoriae, rice, genetic variation, RAPD. |
