Název v původním jazyce

Genetic variation for growth at one and two summers of age in the common carp (Cyprinus carpio L.): Heritability estimates and response to selection

Popis výsledku v původním jazyce

We estimated the heritability of growth-related traits (weight and length at ages one summer, first spring and two summers) in a synthetic mirror carp strain (HSM) in the Czech Republic. The four generation pedigree was obtained from parentage assignmentof three factorial mating designs with microsatellite markers, and included 195 fish without phenotypes (48 G0, 147 G1) and 1321 fish with phenotypes (674 G2, 647 G3). Animal model heritability estimates over generations were in the range 0.21?0.33 forlength and in the range 0.31?0.44 for weight. The genetic correlation between length and weight was high (0.97). The correlations between growth measurements in the first and in the second summer of age were moderate to low (0.34?0.67). Divergent selection for length at two summers of age was performed on G2 fish, and response to selection was evaluated by comparing the offspring of the selected sires in G3, in a communal test where genetic groups were identified by microsatellite parent
