Evaluation of advantages in the growth, survival and reproductive aspects of triploid hybrids derived from Crassostrea gigas tetraploids and C. ariakensis diploids in northern China
Crossbreeding and polyploid breeding are two important tools for the genetic improvement of oysters, and their cross-application is expected to provide new benefits to oyster breeding. To evaluate the aquaculture traits of allotriploids between Crassostrea gigas and Crassostrea ariakensis, two tripl...

Overall, TAG always presents triploid advantages in terms of growth and survival throughout the grow-out stage and shows potential value as a new resource of oyster farming or genetic improvement.

Crossbreeding and polyploid breeding are two important tools for the genetic improvement of oysters, and their cross-application is expected to provide new benefits to oyster breeding. To evaluate the aquaculture traits of allotriploids between Crassostrea gigas and Crassostrea ariakensis, two triploid hybrids (TAG (diploid C. ariakensis 9 x tetraploid C. gigas d) and TGA (tetraploid C. gigas 9 x diploid C. ariakensis d)) were established.
