Embodiment
[0019] A Hepu pearl oyster quantitative trait gene aggregation breeding method, comprising the steps of:
[0020] (1) Collect more than 200 Hepu mother-of-pearl parents from sea areas or farms in Sanya, Beihai, and Xuwen respectively, select individuals with correct shape, integrity, and no disease, and measure the shell length, shell height, and shell width And body weight and other indicators, the F1 generation basic family was constructed by using the diallel cross method with a ratio of male to female at 1:1. Each combination constructs more than 10 families, and the total number of families is 90. The seedling breeding conditions of all families should be controlled under the same conditions as far as possible. When the seedlings reach about 1mm and emerge, they will be moved to the sea area to be cultured in net cages, and the conditions such as stocking density are the same. Other breeding management measures are the same as conventional production.
