Objective：To explore the muscle texture of the crossbreed F1. Method： The female parent grass carp （ Ctenopharyngodon idellus） （ ♀ ） × Barbel chub （ Squaliobarbus curriculus） （ ♂ ） F1 （ crossbreedF1 ） as well as their parents at the same specification were used for our research. The texture analyzer, the freezing sectioning technology and hematoxylin-eosin staining method were used for muscle characterization and fiber diameter. In addition, the spatio-temporal expression of COL1A1, COL1A2, CAST genes were identified by RT-PCR. O...
