Study on the Growth Trait of the Second Generation for Two Selective Breeding Populations of Larimichthys crocea
摘要
Abstract
By comparing the growth trait of the offspring of three breeding populations of Larimichthys crocea, the second generation of two selective breeding populations ( XY2012-JC-F2 , XY2012-XP-F2 ) and the first generation of the wild breeding population ( YS2012-F1 ) , the breeding effects were analyzed .The results showed that the cor-relations of body length ( L) and weight ( W) for F2 and F1 were different based on the measurement results which fitting 4-13 month-old Larimichthys crocea.Growth rate of the selective breeding were higher than the wild popula-tion breeding at the later stage .Analysis of the body length and weight showed that realized heritability of body length for 10 to 13 months of XY2012-JC-F2 was 0.228 -0.364 , realized heritability of weight was 0.131 -0.243;and for XY2012-XP-F2 , realized heritability of body length and weight were 0.193-0.265 and 0.126-0.134,respectively.The correlation coefficient of body length and weight was 0.857-0.981, the maximum corre-lation coefficient of body length and full length for 13 month-old Larimichthys crocea was 0.997.Results indicated that selective breeding had a certain role in the process of breeding .It was also suggested that family selection and within-family selection should be combined in the future breeding .关键词
