    本計畫將利用已建立的海水吳郭魚品系Oreochromis spirulus，及紅色吳郭魚 CP品系Oreochromis niloticus經海水馴養過兩種品系進行全互交，比較各自的自交 及正反交子代的遺傳特性：(1) O. spirulus、CP 和正反交子代的分子標誌等；(2) O. spirulus、CP 和正反交子代等4種的遺傳岐異度、(3)相似度；(4)正反交F1子代( O. spirulus♀ ×CP♂ 和 CP♀ × O. spirulus ♂)的海水適應特性。以作海水吳郭 魚選育及養殖參考。

     The tilapia is the most important commercial culture species for its fast growth, salinity tolerance, stocking density and adaptability. Yet its inheritance phenotype of salinity tolerance is unstable. The overall goal of this project is to establish cross lines with Oreochromis spirulus and O. niloticus a complete diallel cross that could provide genetic resources for future genetic improvement and commercial production.
