F3–F8 hybrids of red crucian carp (Carassius auratus red var.)(♀)× common carp (Cyprinus
carpio L.)(♂) were found to be allotetraploids by examining the numbers and karyotypes of …

Following activation by UV-irradiated sperm, diploid eggs of the allotetraploid hybrids (red
crucian carp♀× common carp♂) developed into normal live gynogens. Cold-shocking …

Results of a 16 year (1977–1992) study of hybrids obtained from crossing two cyprinid fish,
crucian carp, Carassius auratus gibelio (Bloch)(bisexual form), and common carp, Cyprinus …

The establishment of the tetraploid organism is difficult but useful in genetics and breeding.
In the present study, we have artificially established an autotetraploid fish line (F2–F8) …

This study provides genetic evidences at the chromosome, DNA content, DNA fragment and
sequence, and morphological levels to support the successful establishment of the polyploid …

Populations of crucian carp (Carassius auratus gibelio Bloch) from northeast China have a
zygotic chromosome number of 140–156 and appear to be triploid in origin. However …

The development of techniques for production of gynogenetic, androgenetic, polyploid, and
monosex progenies in common carp (Cyprinus carpio L.) is described from a chronological …

Distant hybridization makes it possible to transfer the genome of one species to another,
which results in changes in phenotypes and genotypes of the progenies. This study shows …

A method for mass production of triploid carp was developed by the cold treatment of eggs
after fertilization. Triploidy was demonstrated by cytophotometry and chromosome …

Background Crucian carp (abbreviated CC) belongs to the genus of Carassius within the
family of Cyprinidae. It has been one of the most important freshwater species for Chinese …
