The thermocycler (Biorad MJ Mini thermal cycler,USA) was programmed for an initial denaturation step of 5 minute at 94°C, denaturation at 92°C for 1 minute,annealing for 1 minute at 35°C, extension was carried out at 72°C for 2 minutes and final extension at 72°C for 10 minutes and a hold temperature of 4°C at the end PCR products were electrophoresed on 2% (w/v) agarose gels, in 1X TAE Buffer at 120 V for 2hrs and then stained with Ethidium bromide (0.5μg/ml). Gels with amplicons
were visualized and photographed in Gel Documentation system (Syn gene). Each RAPD product was assumed to represent a single locus and data were scored for
presence (1) and absence (0) of bands. Index of genetic variation was calculated and dendrograms were constructed through UPGMA method using computer software POPGENE (ver. 1.32) of Yeh et al.
