Fertilization breeding method for developing pinctada martensii with yellow inner shells into nacre with dark yellow golden inner shells

Abstract

The invention discloses a fertilization breeding method for developing pinctada martensii with yellow inner shells into nacre with dark yellow golden inner shells. The fertilization breeding method comprises the following steps: 1) selecting male pearl shells and female pearl shells with dark yellow inner shells from a batch of pinctada martensii, performing fertilization breeding in a natural fertilization or artificial fertilization mode, performing separated hanging breeding on the obtained pinctada martensii seeds, and enabling the pearl shells to grow rapidly; 2) at the same stage of a next year, selecting the pinctada martensii seeds, discarding qualified pearl shell seeds such as pearl shells with milky white inner shells and light yellow inner shells, retaining male pearl shells and female pearl shells with dark yellow inner shells, performing breeding again, performing hanging breeding on pearl shell seeds obtained through breeding, and enabling the pearl shell seeds to grow healthily and rapidly; and (3) performing elimination breeding for five generations, and starting pearl breeding when pinctada martensii shells with dark yellow inner shells accounts for about 90% of the obtained pinctada martensii seeds. Pearls bred in the pinctada martensii shells with the dark yellow inner shells are of dark yellow colors or thick golden colors with pearly luster.

Description

technical field [0001] The invention relates to a method for fertilizing and raising seedlings of deep golden-colored pinnacles, in particular to a method for fertilizing and raising seedlings of yellow pinnacles martensii male shells with inner shells to grow dark golden-colored pinnacles with inner shells. Background technique [0002] Over the past ten years, people have become more and more fond of pearl jewelry, and have higher and higher requirements for the quality of pearls. People are no longer satisfied with single white pearls, gold pearls and black pearls have gained people's favor. Among the current pearl varieties, only South Sea golden pearls are natural golden pearls. South Sea golden pearls are in short supply and the price keeps rising. Due to the relatively large body of Kingdee shellfish, farmers routinely implant large pearl nuclei, and the produced Nanyang golden pearls are relatively large in size, with a diameter of about 10-18mm, which is very impo...

Problems solved by technology

However, at present, there is no technology to cultivate golden yellow pearls from the martensitic shell cultured pearls with dark yellow inner shells.
