摘要: Abstract The aim of this study was to estimate the growth trait parameters in grass carp, Ctenopharyngodon idella , which is one major freshwater aquaculture species China. heritability, genetic and phenotypic correlations were estimated for body weight, standard length, height thickness measurements 10 18 month old fish. Analyses performed on a total 41 104 full-sib families carp including 937 2454 individuals at (first spring) 18 months (second winter) age, respectively. reconstructed using molecular pedigree based twelve microsatellite loci, 97.6% offspring unambiguously assigned single parent pairs. Unbalanced contributions progeny found among parents ( P > 0.05). heritability estimates traits ranged from 0.24 0.38, significantly different zero Statement relevance Our article comply with Policy submission manuscripts Genetic Section. In study, we genetic, 18 months. an essential report quantitative analysis sub-adult carp. This paper has not been submitted any other journal publication. authors can confirm that no actual or potential conflicts interest report. All have read agreed contents manuscript consent its
