Embodiment 1

[0025] a. Source and selection of broodstock: In June 2006, 2-year-old clams with regular shell shape and consistent shell color were selected from wild populations (cultured populations) as breeding populations. , put it in the ecological shrimp pond for natural ripening. Sampling was taken regularly to observe gonad development until the gonads matured.

[0026]b. In the last ten days of September 2006, when the gonads of the broodlings were mature, they were stimulated by drying in the shade for 4 hours and running water for 1 hour. After 2-4 hours, the broodlings began to lay eggs and ejaculate. Rinse it with tap water and put it in a 2.0L red plastic bucket filled with fresh sea water. After about 5-15 minutes, the individuals placed alone will continue to lay eggs and ejaculate. A total of 6 were selected, one male and one male and female of Haiyanghong (R), white clam (W), and zebra clam (Z), and 3 hybrid combinations R×Z, W×Z, W×R were established, and 3 selfing combi...

Embodiment 2

[0032] On the basis of Example 1, in late September, 2006, when the gonads of the parental shellfish matured, the sea red and zebra clams (30 each), the pearl white and the zebra clams (30 each), and the Liangdaohong and the zebra clams (30 each) (30 each) were placed in their respective white plastic buckets. After being stimulated by drying in the shade for 8 hours and running water for 1 hour, after 2-4 hours, the brood shellfish began to lay eggs and discharge sperm, thus obtaining 3 population hybrid combinations between two shell-colored strains. The characteristic of this combination is that in addition to the original two shell colors of the parents, the offspring will also have the shell color performance of the hybrid. Others are the same as b, c, d, e, f in embodiment 1. In this way, a large number of hybrid offspring can be obtained, and it is found that the hybrid individuals are significantly larger than the control population. The growth speed of the white zeb...

Abstract

The invention provides a breeding method of a hybridization line of Ruditapes philippinarum. By utilizing qualitative character of shell color as tag, the method takes Ruditapes philippinarum with different shell colors as material, the hybridization line with excellent properties are obtained by monomer hybridization and colony hybridization. In particular, the invention adopts two red lines of pearl white and ocean red which grow rapidly, and zebra clam line with strong stress resistance as material to establish the hybridization line so as to obtain the hybridization line of white zebra and red zebra with the properties of rapid growth speed and strong stress resistances. The hybridization line obtained by the invention is characterized by fast growth speed and high survival rate, thereby effectively improving the yield of Ruditapes philippinarum and laying a solid foundation for breed modification of Ruditapes philippinarum.

Description

technical field [0001] The invention belongs to the category of shellfish culture, and in particular relates to a seed production method of Philippine clams. Background technique [0002] The Philippine clam (Ruditapes philippinarum) belongs to the bivalve clam family, the brocade subfamily, and the clam genus, and belongs to the wide-temperature and wide-salt species. At present, about 90% of the world's about 2 million tons of Philippine clam production comes from farming, and it mainly comes from farming in mainland China (Goulletquer 1997). In 1999, the output of tidal flat shellfish in my country was 2.464 million tons, of which 73% were Philippine clams, accounting for about 18.4% of the total output of mariculture in my country. With the improvement of people's living standards, the domestic and foreign markets are in short supply, and the market potential is huge. However, due to lack of attention to resource protection and indiscriminate harvesting, its natural ou...
