Preliminary study on hybridization between Haliotis sieboldii and Haliotis discus hannai

  • The gametic hybridization between Haliotis sieboldii and Haliotis discus hannai was studied in Pingtan,Fujian in 2005.The results showed that the fertilization rates of Haliotis sieboldii ♂×H.discus hannai♀ and Haliotis sieboldii♀×H.discus hannai♂ were 14.5% and 13.8% respectively,and those autocopulation of the H.sieboldi and H.discus hannai were 80.5% and 75.3% respectively.The survival rates of the hybridization of H.sieboldii and H.discus hannai were higher,the growth rates of the larvae and survival rates of overwintering juvenile abalones of the crossbreeding between H.sieboldii and H.discus hannai were lower than those of the autocopulation of H.sieboldi,and which were significantly higher than those of autocopulation of H.discus hannai,F1 generation of hybridization indicated good production performance and heterosis.
