ABSTRACT

We report total ten isolates of F. semitectum recovered from different hosts. Identity of these isolates was determined by morphological and cultural characteristics and confirmed by RAPD-PCR analysis using forty random primers. Morphologically all the ten isolates showed similarity, but based on RAPD-PCR analysis, these isolates can be categorized in three groups depending upon similarity co-efficient. Genetic similarity coefficients between pair wise isolates varied from 0.00 to 1.95 based on an unweighted paired group method of arithmetic average (UPGMA) cluster analysis. RAPD-PCR technique can be used as an important tool for the genetic differentiation among isolates of F. semitectum.
