The invention discloses a method for breeding improved Pinctada martensii growth traits based on whole genome selection, which comprises the steps of selecting a reference population by measuring phenotype; obtaining SNP locus information in the whole genome range by using a sequencing technology; estimating the effect value of SNP by using three methods of rrBLUP, BayesA and BayesB, and analyzing the accuracy; and then estimating the GEBV of each individual in the reference population. The method can select the pinctada martensii at an early stage, shorten the culture period, reduce the investment, increase the accuracy of character selection and reduce the factors of environmental influence. The GEBV obtained by the method can be used as a standard for breeding improved varieties of growth traits, an effective molecular breeding method is provided for breeding excellent varieties of pinctada martensii with excellent growth traits, the culture yield and the quality of the pinctada martensii are improved, and the green and healthy development of the pinctada martensii culture industry is promoted. |
