We established 11 mating combinations of L. vannamei among 7 different genesis groups using inbreeding and hybridization. The growth performance for female and male among groups in 270 d experiment was compared and analyzed. The populations were selected and graded in the Kung value and comprehensive evaluation values. In addition, selection effect for body weight traits was predicted. The results show that these 11 populations of 270-day-old in age, the body length and body weight was cm and g. The among-population differences in body length and body weight were significant (P<0.05); the regression relationship between body weight and body length was extremely significant (P<0.01), and the regression coefficient reached For each mating combination, t-test analysis was performed on body length and body weight, and the differences were significant or extremely significant. All the populations were assessed as excellent, good, and average levels according to the comprehensive evaluation value. Based on the above analyses, combinations of good sir and dam parents were selected. Moreover, the value of L. vannamei for breeding G 1 generation was g predicted by comprehensive selection response. The results may provide a good reference for the next phase of L. vannamei family selection, and accelerate the process of the genetic improvement. Key words Litopenaeus vannamei; growth; Kung value; selection response; prediction
