Heterosis for Yield and Crossbreeding of the Pacific Oyster Crassostrea Gigas

Hedgecock, D., and J. P. Davis. 2007. Heterosis for yield and crossbreeding of the Pacific oyster Crassostrea gigas. Aquaculture 272S1: S17–S29.

This paper provides major evidence for hybrid vigor in the Pacific oyster and lays the foundation for Pacific Hybreed’s crossbreeding program. Hybrid vigor is the dramatically greater yield, resilience, and uniformity in the offspring of a cross between two inbred parent lines.
