| 论文摘要： | In this study, a stable allotetraploid gibel carp strain was established from allogynogenetic populations of triploid gibel carp clone D. Its modal chromosome number was identified as 208, and the added chromosomes were demonstrated to originate from common carp by internal transcribed spacer-1 (ITS1) and transferrin (Tf) allele sequence analyses. Significantly, its morphological body type and morphometric traits were observed to be similar to that of the maternal gibel carp. And, the new allotetraploid showed remarkable growth superiority by growth rate comparison tests, in which an approximate 22.9-26.6% higher growth rate was found in the allotetraploid strain than that in the maternal allogynogenetic gibel carp. Overall, we have bred an allotetraploid strain that resembles a typical gibel carp body type, and possesses significant growth superiority. Therefore, this study provides an excellent material for fish polyploidy breeding and aquaculture practice. (C) 2016 Elsevier B.V. All rights reserved. |
