Based on Jian carp and Huanghe carp, three populations including selfing of JL(Jian carp♀× Jian carp)，direct cross JH(Jian carp♀× Huanghe carp♂) and backcross HJ(Huanghe carp♀× Jian carp♂) were established and tagged by PIT(passive integrated transponder) system with concerned growth parameters measured on 157，398，598 days after hatching respectively. The major results were as follows. (1) The orders of the growth rates were HJ>JH>JL on 157 and 398 days and the difference between JL and HJ was significant(P<0.05). On 598 days, it turned out to be JL>JH>HJ and the difference among offspring was not significant(P>0.05). (2) CV of body weight and CV of body length shared the same tendency that was HJ>JH>JL on 157 and 398 days and JL>HJ>JH on 598 days. CV of body length was smaller than that of body weight. (3) Fullness increased with time and it was the highest in JL. The difference between JL and JH，JL and HJ was significant. (4) The growth differences between female and male carps were significant. The growth rate of female carps was faster than that of JL all the time, whereas male ones only showed the growth advantage over JL on 157 days and heterosis declined on 398，598 days. (5) The decision coefficient of body length to body weight played a leading role on 398 days. On 598 days, the decision coefficients of body height played a leading role for HJ(♀)，JL(♀) and body length for JL(♂)，HJ♂)，JH(♀). For JH(♂), the decision coefficient of body length and body height were almost the same. (6) Difference of body weight and absolute growth rate of body weight were not significantly influenced (P>0.05) by breeding days, but the influence was h ighly significant (P<0.01) to body length, absolute growth rate of body length, instantaneous growth rate of body weight, CV of body weight, growth index and fullness. The influence produced by different populations and different sex of fish was highly significant to all the growth parameters above.
