Wang Word tiger-head of rejuvenation of: Wang Word tiger-head is one of Beijing's traditional goldfish varieties, because this growth cycle length, to the second instarAbove its characteristics is as other varieties of Goldfish head tiger-head of development and discolored. In the Decade, big fishField to keep, only a small number of breeding hand closed. Several generations of kin breeding results, although get purification, commoditiesZoogeography is maintained. But inbred offspring, manifested by the vitality of the recession, the decline in yield and quality, regress. ABody prematurely appear bags back bow collapse of adverse consequences. Make them lose their ornamental value.
Soochow University aquaculture graduate Wei bin have on different groups of tiger-head genetic diversity for comparative research, applicationMorphological and molecular genetics and Immunology on tiger-head goldfish three geographical groups are compared between the germplasm conservation and breeding geneticsWork has provided some guidance. He with the help of microsatellite DNA Molecular markers, and other molecular genetics methods on its group to study genetic relationship, Hangzhou, Suzhou, Nantong, and tiger population genetic background a difference, it is recommended that you divide Suzhou tiger-head goldfish and Nantong groups crossing, with a view to get a high genetic diversity, strong hybrid art.
Apply the same theory, find other line (or similar) from source hybrid is Wang Word tiger-head of deteriorationOne way.
