Using microsatellite markers with 10 pairs of primers,genetic structure of Oreochromis niloticus,Sarotherodon melanotheron and their hybrids were *** results suggested that:① Six pairs of primers showed a rich polymorphic,which can be used as genetic markers for the genetic diversity study of these tilapias.② The analysis based on the six pairs of primers showed that the average heterozygosity(H)ranged as:*** ♀× ***♂(0.725),*** ♀ × *** ♂(0.692),***(0.537),***(0.485).The highest effective numbers of alleles(Ne)existed in ***♀×***♂(3.79),the lowest existed in ***(1.92).The average polymorphism information content(PIC)of 4 tilapias was 0.584,the rank from high to low as,*** ♀ × *** ♂(0.668),*** ♀× *** ♂(0.643),***(0.375),***(0.333).③ The fact of enhanced heterozigosity of hybrids suggested that there were the genetic basement of cross breeding in tilapia.
