Abstract
The invention relates to a method for breeding sound cell small sheet shell for seawater pearl. It comprises following steps: breeding parental generation with India Malpighian mother-of-pearl shell and wild Malpoghian mother-of-pearl shell in Tri-pacific or China, establishing two mating strains through multi-generative breeding and purification; taking female mother-of-pearl shell in India as female parent, and taking male mother-of-pearl shell in Tri-Pacific or China as male parent for hybridization; the got son generation is sound cell small sheet shell, which can effectively increase the growth rate. The shell growth of seawater pearl taking the pallium of said cell small sheet shell as nuclear-filling in sheet is fast, the color id pearl is good and factor of merit is high.
Description
Technical field
The present invention relates to a kind of breeding method of cultivating the good cell piece shell of sea water pearls, especially can improve growth rate, outer embrane with this piece shell is fast for interval velocity on the slotting nucleus small pieces cultivation sea water pearls, nacre color good (pink or silvery white), excellent pearl rate height.
Background technology
China is since nineteen sixty-five is successfully carried out the artificial breeding of pteria martensii, the sea water pearls aquaculture development is rapid, particularly after the nineties in last century, sea water pearls is cultured becomes one of mariculture pillar industry of Guangdong, the coastal some areas in Guangxi and Hainan, and sea water pearls becomes the staple product of foreign exchange earning.After 21st century, the output and the quality of China's sea water pearls aquaculture obviously descend, and reduce gradually in the competitiveness of international pearl market, and the breeding enterprise benefit glides year by year, causes the sea water pearls aquaculture to present serious atrophy trend.Cause the reason of this phenomenon excessive except that cultivation density, outside breeding environment deterioration and cultural technique fall behind, the reason that also has following emphasis: first, applying of artificial propagation and seedling growing process, make the production unit interests that live in the present, close shellfish (be mainly and culture close shellfish) breeding and seedling with only a few, cause inbreeding, culture nacre germplasm serious degradation, make pinctada survival rate, receive pearl index, commodity pearl and high-quality pearl ratio and obviously descend, and thin layer pearl, dirty pearl, lopsided pearl, the high phenomenon of small-sized pearl rate are on the rise; Its two, the sea water pearls industry is always only heavily cultured, not heavily breeding, no improved seeds can be sayed; Its three, inbred production in the random exchange of spat that any diffusion and each sea area in each sea area do not produce between commensurate, causes the natural population genetic structure to destroy with shellfish, genetic diversity reduces, and seriously influences the germplasm quality.
In order to suppress the declining trend of sea water pearls aquaculture industry, promote China's sea water pearls industry to continue healthy development, must carry out the genetic improvement and the improved seeds cultivation work of pteria martensii by persistence.Just be based on pressing for of this reality, under the support energetically of national high-tech plan (863 Program) and National Foundation etc., carrying out the fine-variety breeding work of pearl shell, cultivating good cell piece shell.
Summary of the invention
The purpose of this invention is to provide a kind of breeding method of cultivating the good cell piece shell of sea water pearls.
The technical solution adopted for the present invention to solve the technical problems is: the cell piece shell that will be used for sea water pearls production carries out seed selection with pinctada respectively by its different economic characters.The method of cell piece shell breeding: select to have obvious morphological feature difference two pteria martensii populations with suitable affiliation (be India culture population and Sanya or in homemade wild stocks) be the parent, wherein culture the pteria martensii of population more than continuous 3 generations with India, the good female individuals of selecting excellent mixing seed selection and purifying in excellent is for maternal, with the Sanya or in homemade wild pteria martensii more than continuous 3 generations, the good male that selects excellent mixing seed selection and purifying in excellent is a male parent, form 2 supporting systems, carry out line cross, obtain to have heterotic cell piece shell.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
A kind of flow process of breeding method of the good cell piece shell of cultivating sea water pearls:
F
1: the first filial generation of parent's (male parent and female parent) post-coitum, F
2: F
1For individual first filial generation, F for the generation of parent's post-coitum
3: F
2For individual first filial generation for parent's mating generation.Parent's cultivation and purifying can carry out with this route continuously, produce F
nGeneration.
1. hybridize maternal seed selection and purifying (the shellfish population is cultured by India, mixes seed selection);
Hybridization seed selection of male parent and purifying (Sanya or in homemade wild shellfish population, mix seed selection);
3. the selection cross of good cell piece shell.
Fig. 1 is the flow chart of maternal seed selection of hybridization and purifying (the shellfish population is cultured by India, mixes seed selection);
Fig. 2 be the hybridization seed selection of male parent and purifying (Sanya or in homemade wild shellfish population, mix seed selection) flow chart;
The selection cross flow chart of the good cell piece shell that Fig. 3 is.
The invention has the beneficial effects as follows, mix seed selection and purifying by this parent, set up 2 supporting systems, by line cross, obtain hybrid generation, be good cell piece shell, can improve growth rate, outer embrane with this cell piece shell is fast for the sea water pearls upper strata of inserting the cultivation of nuclear small pieces, nacre color good (pink or silvery white), high-quality pearl rate height.
Embodiment
From away from culture the marine site gather wild Sanya or homemade population pteria martensii, therefrom select 50 of good female individuals of proterties to be male parent, female-male proportion 2.5: 1 for maternal, 20 of males; Wash and sterilize be placed on natural spawning in the same pond, row is smart and fertilization, the offspring that hatching brings out is its first filial generation SS
