Comparative analysis of growth, muscle nutrient composition, and skin transcriptome in f1 hybrids of ctenopharyngodon idella with two different body colors

summary To investigate the characteristics of growth performance, muscle quality, and color related gene expression in the F1 generation of three grass carp families with two different body colors, this study aimed to Build a golden grass carp（ ♀) Golden grass carp（ ♂) [Ctenopharyngodon idella var.gold ( ♀) ×C. idella var.gold ( ♂)] F1 generation (GG), golden grass carp（ ♀) Common body color grass carp（ ♂) [C. idella var.gold ( ♀) ×C. idella ( ♂)] F1 generation (GB) and common body color grass carp（ ♀) Common body color grass carp（ ♂) [C. idella ( ♀) ×C. idella ( ♂)] The growth characteristics, muscle quality, and skin transcriptome features of three F1 (BB) families were systematically analyzed using morphological, nutritional, and RNA seq techniques. The results showed that: (1) in terms of growth performance, the GG family had significantly higher weight gain rate and specific growth rate than the BB and GB families (PBB>GB; (2) In terms of muscle quality, the GG family has significantly higher water content (P
