Amplified PCR products were visualized and photographed under ultraviolet light (Bio-Rad Molecular
Imager XR+ system).after electrophoresis [1.2 % agarose (w/v; SinaClon) plus 1 µg ml−1 ethidium bromide; Merck, Germany]. A 1-kb (for SCoTs) or 100-bp (for ISSRs) DNA ladder (SinaClon) was used as molecular weight ruler.
