Heritability estimates for growth-related traits using microsatellite parentage assignement in juvenile common carp (Cyprinus carpio L.)
Original language description
Common carp is one of the leading species in world aquaculture, but selective breeding for growth rate has not been actively pursued in this species after unsuccessful selection experiments. We estimated heritability for growth-related traits at 8 weeksof age in Hungarian Synthetic Mirror carp at Vodnany (Czech Republic). Parentage assignment with eight microsatellite markers was used in a full factorial cross of 10 dams x 24 sires. Out of 550 offspring, 95.3% could be assigned to a single parental pair. Animal model heritability estimates were 0.33 +/- 0.08 for weight 0.33 +/- 0.07 for length and 0.37 +/- 0.07 for Fulton's condition factor (K). Maternal effects and dominance were not significantly different from zero. The genetic correlation betweenweight and length was 0.98, and negative correlations were found between K and length (- 0.38) and K and weight (- 0.17). It is concluded that selective breeding for increased weight gain can be successful in juvenile carp, using indirect

Czech description
Kapr obecný je jedním z hlavních druhů světové akvakultury, ale selektivní šlechtění na růst bylo po několika neúspěším zastaveno. V článku jsou popsány metody použité u nás a naznačeny možnosti využití výsledků pro šlechtění kapra na vyšší růstovou výkonnost.
