研究分析了唇(♀)×花(♂)杂交育种的特点和可行性。结果表明:2008-2011年,共计获得约164万粒受精卵,杂交F1鱼苗111.7万尾。在水温18～26℃条件下,唇(♀)×花(♂)的催产率、受精率和孵化率可达到85.5%～89.2%、80.6%～81.2%和80%～85.6%。在水温(20±1)℃条件下,杂交F1受精卵在受精后94h10min,仔鱼开始出膜。初孵仔鱼全长5.75～6.83mm。杂交F1成鱼的体色和体型与母本比较相近。唇(♀)×花(♂)的杂交育种是可行的。
The characteristics and feasibility of hybrid breeding of Lip (♀) × Scape (♂) were studied and analyzed. The results showed that a total of about 1.64 million fertilized eggs and 1,117,000 hybrid F1 fry were obtained from 2008 to 2011. The rates of fertilization, fertilization and hatching could reach 85.5% -89.2%, 80.6% -81.2% and 80% -85.6% under the condition of water temperature 18 ~ 26 ℃. Under the condition of water temperature (20 ± 1) ℃, larvae started to membrane after hybrid F1 fertilized eggs 94h10min after fertilization. The total length of newly hatched larvae is 5.75 ~ 6.83mm. F1 adult F1 hybrid fish body color and body size are similar. Cross-breeding of Lip (♀) × Scape (♂) is feasible.
