Preliminary study on hybridization between Haliotis sieboldii and Haliotis discus hannai
-
摘要: 2005年在福建省平潭县对日本西氏鲍(Haliotis sieboldii)与皱纹盘鲍(Haliotisdiscus hannai)进行了杂交试验。结果表明,皱纹盘鲍♀×西氏鲍♂和西氏鲍♀×皱纹盘鲍♂的受精率分别为14.5%和13.8%,西氏鲍和皱纹盘鲍自交的受精率分别为80.5%和75.3%。杂交鲍成活率高、生长速度和越冬成活率均略低于日本西氏鲍,而明显高于皱纹盘鲍,显示出了良好的生产性状和一定的杂种优势。Abstract: 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.
