摘要: The Japanese scallop Patinopecten yessoensis was introduced form Japan to China in 1982. Because of the limitednumber of foundation population, the genetic variability has been lost during hatchery production. For restoring the genetic diversity of Japanese scallop in China, some means and steps for seed yielding, such as re-introducing Japanese wild population from Japanese as parents or hybridizing Chinese hatchery population (♀) with Japanese wild population (♂),were adopted by hatching plant. In this study, seven microsatellite lociwere used to investigate the genetic variations of two different populations, namely, one Japanese hatchery population which parents came fromJapanese wild population, one hybrid population fromChinese hatchery population (♀) and Japanese wild population (♂), and to compare with one Chinese hatchery population and one natural seed population from Dalian in China. The average effective allele numbers per locus (Ae) of the above corresponding populations were 3.753, 3.523, 3.156 and 3.593, the average expected heterozygosities (He) were 0.701, 0.696, 0.669 and 0.701, respectively. These data explained that the seed breed from Japanese wild population as parents had obvious high level genetic diversity than the Chinese hatchery population, and except for the Chinese hatchery population, the genetic variations of the others had no obvious variance.
