Abstract:
Crosses between full-sib (FS) families were tested as a practical method of utilizing non-additive genetic variation for the improvement of growth rate in the European race of the common carp and its hybrid with the Chinese race of the same species. Differences in weight gain among progenies of these crosses ranged from 20% above to 11% below the average of all the tested groups. The interracial hybrid progenies were more uniform than the European progenies, and most of them exhibited faster growth rate. Although the mean hybrid performance was superior, some European groups were just as good as the best hybrids. Since purebred and hybrid progenies were generated from FS parents of known performance, estimates of the regression of offspring to parents could be computed, but no significant regression coefficients were found. The results provide an empirical support for selection between crosses of FS families as an effective breeding method to take advantage of non-additive genetic variation at a selection plateau. © 1981.
