Abstract
A selective breeding method of a new strain of Crassostrea gigas with orange left and right shells includes: selecting individuals of C. gigas with purple left shell and black mantle as the male broodstocks and individuals of C. gigas with black left shell and black mantle as the female broodstocks from cultured populations to generate a F1 family by applying single-pair mating strategy; selecting individuals with black purple left and right shells and black mantle from the F1 family as broodstocks to generate F2 families through family selection; selecting individuals with black purple left and right shells and black mantle from the F2 families as broodstocks to generate F3 families through family selection; and selecting individuals with orange left and right shells from the F3 families as broodstocks to propagate to generate a new strain of C. gigas with the stably inherited trait of orange left and right shells.
