Abstract
A total of 113 novel EST-derived simple sequence repeat (EST-SSR) markers were developed in the Pacific oyster (Crassotrea gigas). Polymorphisms of these markers were evaluated in a wild population of 30 individuals. The number of alleles per locus ranged from 2 to 27 with an average of 6.3, and the observed and expected heterozygosities varied from 0 to 0.9667 and from 0.0333 to 0.9701, respectively. Mendelian segregations were tested for 24 of the markers that were polymorphic in one family produced by single-pair mating. Null alleles were discovered at four loci. Nine tests of segregation ratios revealed significant departures from expected Mendelian ratios. As a useful addition to the collection of the microsatellites that are now available for C. gigas, these EST-SSR markers will help the advance in investigation of QTL mapping and genetic diversity in this species.
