ABSTRACT
In the present paper, the genetic diversity of 48 Beauveria bassiana strains from different altitudes and at different seasons in Dabie Mountains of western Anhui was estimated using inter-simple sequence repeat (ISSR) markers. Twelve among 33 ISSR primers were chosen for their reproducibility and high polymorphism. Seven (2 - 11) markers per primer were scored, and a total of 84 fragments were amplified, in which 73 (81%) were polymorphic. Genetic diversity analysis revealed a relatively high level of intraspecific genetic diversity of B. bassiana in Dabie Mountains of western Anhui the percentage of polymorphic loci (PPL) was 81%, Nei's genetic diversity (He) was 0.3187 and Shannon's genetic diversity index (I) was 0.4782. The genetic differentiation, Gst was 0.1028, indicating that a low degree of genetic differentiation occurred in the B. Bassiana among populations.
