海水珍珠是海水养殖中的主要产业之一,其极高的经济价值众所周知。九十年代以来,随着养殖规模的不断的扩大,在提高产值的同时,也带来了一系列的问题,特别是母贝死亡率高、贝体变小、病害增多、脱核率高、污珠多、成珠率低等种质资源的退化问题。另外二倍体合浦珠母贝的性腺发育,消耗大量能量,每年两个繁殖期所形成的生殖细胞严重影响插核手术的进行,缩短了可插核的时间。水产养殖品种的种质退化问题早已引起国内外有关方面的普遍重视。在国外,日本是珍珠养殖技术和生产极其发达的国家,但由于种群退化和环境污染,养殖成本居高不下,近年来年产珍珠仅10吨左右。因此,从1989年开始,日本遗传育种专家古丸明、和田克彦等进行了合浦珠母贝三倍体的研究。 Sea water Pearl is one of the major industries in marine aquaculture, and its high economic value is well known. Since the 1990s, with the continuous expansion of farming scale, a series of problems have been brought about while raising the output value. In particular, the mortality rate of mothers is high, the size of shellfish becomes smaller, the number of diseases is increased, the rate of delinking is high, Degradation of germplasm resources, such as more dentritic beads and lower beading rates. In addition, the diploid Pinctada hermaphrodite gonadal development, consume a large amount of energy, the annual reproductive cells formed during the two reproductive cells seriously affect the conduct of nuclear insertion surgery, shortening the time of insertable nucleus. The problem of germplasm degradation of aquaculture species has long aroused universal attention from relevant parties both at home and abroad. Abroad, Japan is a country where pearl cultivation technology and production are extremely developed. However, due to population degeneration and environmental pollution, the cost of breeding is still high. In recent years, pearl production is only about 10 tons annually. Therefore, since 1989, Japanese genetic breeding experts such as ancient Maruyuki, Wada Kobayashi and other carried out a study of Triploid Noboru.
