摘要
目前尚未见关于刺参低盐家系建立的报道,本实验采用巢式的配对方法建立低盐刺参半同胞家系9个,共36个全同胞家系以及4个对照组,分别饲养于21‰、24‰、27‰、30‰四个不同盐度下。对体长、体重定期进行测量、分析。结果表明:不同低盐刺参家系在不同盐度环境下的生长差异显著。在21‰盐度下,5、7号家系具有明显的优势;在24‰盐度下5、7、9号家系具有明显的优势;在27‰盐度下7、11号家系具有明显的优势;在30‰盐度下9号家系具有明显的优势。通过分析发现,7、11号家系在低盐环境下的生长表现优秀,可以作为进一步进行耐低盐家系选育的材料。
In accordance with the classic nested design bred 9half--sib families and 4 control group,total 40 full--sib,reared in four different salinity（21‰、24‰、27‰、30‰）. To the length of body, the body weight carry on the survey, the analysis regularly. The results showed that there was significant different in grouth between four different salinity. Under 21‰ salinity, family 5.7 have the obvious superiority; Under 24‰o salinity,family 5.7.9 have the obvious superiori- ty; Under 27‰ salinity,family 7,11 have the obvious superiority; Under 30‰ salinity,family9 has the obvious superiority. Through the analysis discovery, 7.11 are the familise with the best growth traits under the low--salinity, they were also considered as the materials for further selective breeding.
