THE EFFECT OF HETEROSIS IN INTER-LINE CROSSING OF COMMON CARP

Abstract

Three inter-line crossbred populations of common carp were compared with their parent lines during three years of rearing. The effect of heterosis was assessed in the growth rate, survival and share of slaughter yield. Positive effects of heterosis in growth rate and survival of all carp crosses were observed. Share of flesh in the whole body weight was higher only in one group comparing to both parent lines.
