Comparative Study on Juvenile Growth and Heterosis of Oxyeleotris marmoratus, O.lineolatus and the Hybridization (O.marmoratus ♀ ×O.lineolatus♂)
摘要
Abstract
The growth characteristics of three Oxyeleotris groups including the selfing of MM (O. marmoratus ♀ × O. marmoratus ♀ ), the selfing of LL (O. lineolatus ♀ × O. lineolatus 5 ) and their cross ML (O. marmoratus ♀ ×O. lineolatus ) were determined. Results after 35 days of grow-out showed that the final mean weights were higher for the ML (1.6496±0.0501g) than the MM (0.9353±0.1426 g) and the LL (0.6690±0.0687 g). The length of ML was(53.63±0.83) mm, MM was (42.99±2.21) mm, LL was (69.70±4.47 ) mm. The results of the experiment showed that the heterosis was 105.65%. The growth rate of the cross compared with the self fertilized was improved up to 76.37% for MM and 146.58% for ML. The juvenile of crossbreed F1 is a good variety in growth-performance.关键词
