| 英文摘要 | To quantify the response to selection,heritability and genetic correlations between weight and size of Litopenaeus vannamei,the body weight (BW),total length (TL),body length (BL),first abdominal segment depth (FASD),third abdominal segment depth (TASD),first abdominal segment width (FASW),and partial carapace length (PCL) of 5-month-old parents and of offspring were measured by calculating seven body measurings of offspring produced by a nested mating design.Seventeen half-sib families and 42 full-sib families ofL.vannamei were produced using artificial fertilization from 2-4 dams by each sire,and measured at around five months post-metamorphosis.The results show that heritabilities among various traits were high:0.515士0.030 for body weight and 0.394士0.030 for total length.After one generation of selection,the selection response was 10.70% for offspring growth.In the 5"' month,the realized heritability for weight was 0.296 for the offspring generation.Genetic correlations between body weight and body size were highly variable.The results indicate that external morphological parameters can be applied during breeder selection for enhancing the growth without sacrificing animals for determining the body size and breed ability;and selective breeding can be improved significantly,simultaneously with increased production. |
