In order to study the Inheritance of Microsatellite Markers in the hybrid of Chalcalburnus chalcoides and Vimba vimba persa in the Southern part of the Caspian Sea, hybridization between the species was carried out during spring (2009) in Shahid Ansari reproduction and culture workstation. 30 samples from the produced larva and also small piece of dorsal and pectoral fin of their parents were collected and stored in pure ethanol (96%) and transferred to the biotechnology of the Caspian Ecology Academy. DNA was extracted from fin samples of the parents, whilst the whole F1 progeny was used to isolate the DNA by Phenol-chloroform method. Quantity and quality of extracted DNA was determined using 1% Agarose electrophorus. DNA was used for PCR ampilification of 10 microsatellite loci. The amplifications were run on 6% Polyacrylamid electrophorus. The present study showed that 7 out of 10 markers were polymorphic and variated between the parents. Goodness of fit to the Mendelian inheritance ratio was determined by X2 analysis. 4 primers were segregrated according to Mendelian expectations at a significance level of P¡Ü0.05. Based on UPGMA dendrogram (Nei, 1978) two different clusters were obtained in which Chalcalburnus chalcoides and hybrid were in the same cluster but Vimba vimba persa was in the other. It seems that Vimba vimba persa is a joint ancestor for these two. High heterozygosity presence in parents and their F1 shows the high potential of genetic variety in Chalcalburnus chalcoides and Vimba vimba persa which from the aquaculture management and conservation view is important and considering the high genetic variety in their hybrid, the hybrid has the sufficient potential for race improvement.
