So it is very necessary to study variances of Chinese Meretrix meretrix germplasm resources and their molecular genetic bases for their lasting utilization,sustained and healthy development of aquaculture industry. In this study, the genetic bases and their variances of representative populations of Meretrix clam were investigated through phenotypic traits and on the molecular level by quantitative genetic methods and molecular marker analysis technique.

本研究从表观性状和分子水平上探测我国文蛤种质资源的遗传基础和变异水平，旨在深入了解我国文蛤的种质状况并为其保护和可持续利用提供依据；在此基础上，通过杂交选择育种实践，分析和探讨文蛤由此获得杂种优势水平，为养殖文蛤的遗传改良和新品种培育提供理论指导。
